People searching for 7HP ingredients explained may initially believe that the product contains only the three ingredients shown in its commercial title: minoxidil 7%, dutasteride 0.1% and horse placenta extract.
The current official ingredient panel for 7HP Hair Regrowth Treatment lists four active ingredients:
- Minoxidil USP 7% w/w
- Horse Placenta Extract 1.67% w/w
- Dutasteride 0.1% w/w
- Oxytocin 0.1% w/w
That distinction matters because oxytocin is not merely an inactive carrier or fragrance ingredient. It is listed as an active ingredient, yet it has the least established clinical hair-loss evidence of the four.
7HP is built around a multi-pathway formula:
Minoxidil 7%
↓
Follicular growth stimulation
Dutasteride 0.1%
↓
DHT-pathway inhibition
Horse Placenta Extract 1.67%
↓
Peptide, protein and growth-factor support concept
Oxytocin 0.1%
↓
Experimental follicular-signalling concept
These pathways are scientifically different, but their evidence is not equal.
Minoxidil has the strongest direct topical evidence.
Dutasteride has established DHT-inhibiting pharmacology and growing topical research, but the exact 7HP formulation has not been shown publicly to have the same clinical results as studied topical dutasteride solutions.
Horse placenta has indirect laboratory and limited formulation research involving different species and delivery systems.
Oxytocin has emerging cell and hair-follicle-organoid evidence rather than established human scalp-treatment evidence.
The correct description is therefore:
7HP combines one established topical hair-growth medicine, one potent but non-standard topical DHT inhibitor and two experimental biological-support actives.
Direct Answer
With 7HP ingredients explained accurately, the formula contains four active ingredients rather than only the three highlighted in its commercial title.
The current official formula lists:
| Active ingredient | Concentration | Intended role |
| Minoxidil USP | 7% w/w | Follicular growth stimulation |
| Dutasteride | 0.1% w/w | Type I and II 5-alpha-reductase inhibition |
| Horse Placenta Extract | 1.67% w/w | Peptide, protein and growth-factor support concept |
| Oxytocin | 0.1% w/w | Experimental follicular signalling |
The product is directed as five sprays applied twice daily to thinning scalp, followed by two to four minutes of massage. Using more or applying it more often is specifically stated not to improve results.
However, the public pages do not disclose:
- Millilitres delivered by one spray
- Whether five sprays equal exactly one millilitre
- Milligrams of each active per application
- Total daily dutasteride exposure
- Total daily oxytocin exposure
- Amount of horse placenta applied daily
- Human 7HP pharmacokinetic data
- Serum dutasteride concentration
- Serum or scalp DHT changes
- Oxytocin absorption
- A randomised trial of the complete 7HP formula
The percentages explain what is present in the bottle. They do not by themselves establish the amount entering the scalp or bloodstream.
7HP Ingredients Explained: What the Official Formula Confirms
The official manufacturer page provides the following formula:
Active Ingredients
- Minoxidil USP 7% w/w
- Horse Placenta Extract 1.67% w/w
- Dutasteride 0.1% w/w
- Oxytocin 0.1% w/w
Other Ingredients
- Deionised water
- Propylene glycol
- Ethanol
- Peppermint oil
- Menthol
- African pepper extract
Official Application Directions
Five sprays
↓
Apply directly to the thinning scalp
↓
Repeat twice daily
↓
Massage for two to four minutes
↓
Do not exceed the recommended amount
The manufacturer also states that continued use is necessary to maintain minoxidil-related benefit.
General Brand Instructions Requiring Label Confirmation
The Regrowth Labs FAQ says its leave-in treatments are generally:
- Applied to a dry scalp
- Used at one millilitre or five sprays per dose
- Left on for at least four hours before washing
- Used twice daily
Those instructions appear consistent with 7HP’s five-spray schedule, but the physical bottle should confirm:
- Five sprays equal one millilitre
- Four-hour leave-in time applies specifically to 7HP
- The scalp should be completely dry
- The same dose covers the entire intended treatment zone
Why the Commercial Title Omits Oxytocin
The manufacturer’s page title presents 7HP as:
Minoxidil 7% + Dutasteride 0.1% + Horse Placenta 1,000 mg.
The active panel additionally includes oxytocin 0.1% w/w.
There are several possible explanations:
- The title highlights only the three principal marketing ingredients.
- Oxytocin may be considered part of the placenta or stress-support concept.
- The product title may not have been updated when the active panel changed.
- The active panel may contain inherited information from another product.
The website alone cannot determine which explanation is correct.
Before publication:
- Inspect the front label.
- Inspect the back ingredient panel.
- Check the outer box.
- Review any patient or product leaflet.
- Confirm the batch formula with Regrowth Labs.
- Confirm that oxytocin 0.1% appears on current UAE stock.
The article should retain oxytocin because it appears in both the official and UAE ingredient panels.
Minoxidil 7%: Established Ingredient, Less-Established Strength
Minoxidil is the best-established active within 7HP.
Topical minoxidil is widely studied for androgenetic alopecia, but recognised regulatory and clinical evidence centres mainly on:
- 2% topical solution
- 5% topical solution
- 5% topical foam
A 7% concentration is higher than standard 5% minoxidil, but the number does not automatically mean:
- Forty per cent more hair growth
- Faster results
- Deeper penetration
- Better hairline response
- Better crown response
- Greater effectiveness for every user
The exact finished 7HP product would need direct comparative testing.
Does 7% Minoxidil Work Better Than 5%?
That has not been established by the reviewed 7HP information.
Higher-strength minoxidil does not always produce better outcomes. In one randomised 36-week study, 5% topical minoxidil was moderately superior to 10% minoxidil for several measured hair-count outcomes, while irritation was more marked with the 10% solution.
That study does not directly compare 5% with 7%.
It does show why a higher percentage should not be treated as automatic superiority.
Relevant factors include:
- Vehicle
- Solubility
- Scalp penetration
- Applied volume
- Irritation
- Adherence
- Product stability
- Individual sulfotransferase activity
- Treatment duration
- Diagnosis
The broader strength discussion belongs in the Minoxidil Treatment Guide.
Concentration Is Not the Same as Daily Dose
The official formula states 7% w/w.
That means minoxidil accounts for seven per cent of the product’s weight.
The applied dose still depends on spray output:
7% w/w concentration
×
Verified weight delivered by five sprays
=
Minoxidil applied per administration
The same calculation applies to dutasteride, placenta and oxytocin.
Without grams or millilitres per five sprays, the article cannot accurately state:
- Milligrams of minoxidil per dose
- Milligrams of dutasteride per dose
- Milligrams of oxytocin per dose
- Total daily exposure
Do not assume that five sprays from every bottle always equal one millilitre unless the applicator has been validated.
Minoxidil’s Mechanism Should Not Be Reduced to Blood Flow
The current product copy says minoxidil increases blood circulation and delivers oxygen and nutrients to follicles.
Vascular effects may contribute to minoxidil pharmacology, but the hair-growth mechanism is more complex and not fully explained by increased circulation alone.
Minoxidil is associated with:
- Potassium-channel activity
- Hair-cycle effects
- Anagen support
- Changes in follicular signalling
- Conversion into minoxidil sulphate within follicular tissue
Use:
Minoxidil supports follicular activity and the growth phase through several biological pathways.
Avoid:
Minoxidil simply feeds follicles with extra blood.
Minoxidil Safety Warnings
The official 7HP page warns against use in people with heart disease or those taking blood-pressure-lowering medicines. It directs users to stop treatment and see a doctor after chest pain or a rapid heartbeat.
Standard topical-minoxidil warning categories also include:
- Dizziness
- Faintness
- Swelling of the hands or feet
- Sudden unexplained weight gain
- Persistent scalp irritation
- Unwanted facial hair
The exact frequency of those effects cannot be assigned to 7HP because its formulation and concentration differ from standard 5% products.
Seek urgent medical assistance for:
- Severe chest pain
- Fainting
- Breathing difficulty
- Severe facial swelling
- A serious allergic reaction
- Accidental ingestion
Dutasteride 0.1%: The DHT-Targeting Active
Dutasteride inhibits 5-alpha-reductase, reducing the conversion of testosterone into dihydrotestosterone, or DHT.
DHT contributes to progressive follicular miniaturisation in genetically susceptible male androgenetic alopecia.
The simplified pathway is:
Testosterone
↓
Type I and Type II 5-alpha-reductase
↓
DHT
↓
Androgen signalling in susceptible follicles
↓
Progressive miniaturisation
Dutasteride inhibits both type I and type II 5-alpha-reductase.
Product-Page Mechanism Error
The current 7HP pages describe dutasteride as inhibiting types I, II and III.
The standard clinically recognised description is dual inhibition of:
- Type I
- Type II
The type III wording should be removed unless a strong, relevant primary source and clinically meaningful explanation are added.
Is Topical Dutasteride Proven for Hair Loss?
Topical dutasteride research is developing.
A 2025 phase II randomised trial studied daily topical dutasteride solutions at:
- 0.01% w/v
- 0.02% w/v
- 0.05% w/v
The 0.05% formulation improved target-area hair outcomes compared with placebo and oral finasteride in that specific 24-week study. The study also reported modest serum testosterone and DHT changes with the topical solutions.
This is relevant evidence for topical dutasteride as a treatment concept.
It does not directly validate 7HP because 7HP uses:
- Dutasteride 0.1% w/w
- Minoxidil 7%
- Horse placenta
- Oxytocin
- A different vehicle
- Five sprays twice daily
- A different application amount
The studied 0.05% solution and 7HP 0.1% formula are not interchangeable.
Why 0.1% Does Not Mean Twice the Clinical Effect of 0.05%
A numerical comparison may suggest:
0.1% ÷ 0.05% = 2
That only means the stated percentage number is twice as large.
It does not prove:
- Twice the scalp DHT reduction
- Twice the hair count
- Twice the efficacy
- Twice the systemic exposure
- Twice the side-effect risk
- Better follicular penetration
Vehicle, application volume, unit basis, frequency and skin absorption all influence exposure.
Topical Does Not Mean Systemic Exposure Is Zero
The 2025 topical-dutasteride study detected modest serum hormonal changes, demonstrating that a topical route does not automatically mean zero systemic biological effect.
The reviewed 7HP pages do not provide:
- Plasma dutasteride concentration
- Serum DHT changes
- Scalp DHT changes
- Semen-parameter monitoring
- Long-term systemic safety
Do not state:
- Dutasteride remains only inside the scalp
- 7HP cannot cause systemic effects
- 7HP has no sexual side effects
- Topical dutasteride is automatically safer than oral dutasteride
- 7HP has lower serum exposure than every oral or topical product
Dutasteride Sexual and Psychiatric Warnings
The UK MHRA strengthened warnings for finasteride and dutasteride in May 2026.
The updated guidance advises clinicians and patients to consider:
- Sexual dysfunction
- Depressed mood
- Suicidal thoughts
- The need to review psychiatric history
- Ongoing monitoring during treatment
For 7HP, users should report:
- Reduced sexual desire
- Erectile difficulty
- Ejaculation changes
- Testicular symptoms
- Breast tenderness or enlargement
- Significant depression
- Severe anxiety
- Suicidal thoughts
The exact frequency for topical 7HP is unknown.
Suicidal thoughts or thoughts of self-harm require urgent support.
Pregnancy and Household Transfer
Dutasteride exposure is a serious concern during pregnancy because inhibition of DHT may affect development of the external genitalia of a male fetus.
A wet topical spray can transfer through:
- Hands
- Fingernails
- Forehead skin
- Wet treated hair
- Pillows
- Towels
- Caps
- Helmets
- Bathroom surfaces
- The spray nozzle
Practical precautions include:
- Pregnant individuals should not apply 7HP.
- Wash hands thoroughly after use.
- Clean under the fingernails.
- Remove accidental facial drips.
- Allow the scalp to dry before lying down.
- Avoid sharing a recently used towel.
- Keep the bottle away from children.
- Clean spills immediately.
- Seek professional advice after pregnancy-related exposure.
The exact household-transfer risk from 7HP has not been measured publicly.
Horse Placenta Extract 1.67% w/w
Horse placenta is the formula’s most distinctive animal-derived ingredient.
The manufacturer describes it as containing:
- Amino acids
- Peptides
- Proteins
- Fatty acids
- Carbohydrates
- Mucopolysaccharides
- Vitamins
- Minerals
- Nucleic acids
- Enzymes
- Growth-related factors
This is a manufacturer ingredient description.
It does not establish that every listed compound:
- Remains active after processing
- Is present at a clinically relevant amount
- Survives storage
- Leaves the alcohol-water vehicle
- Penetrates human scalp
- Reaches the lower follicle
- Improves human hair counts
- Strengthens scalp immunity
What Does Horse Placenta 1,000 mg Mean?
The product title states horse placenta 1,000 mg, while the ingredient panel states 1.67% w/w.
These figures would approximately align if the total product weight were around 60 grams:
60 g total product
×
1.67%
=
1.002 g placenta extract
1.002 g
=
approximately 1,000 mg
That calculation is conditional.
The physical bottle must confirm:
- Net product weight
- Whether 1,000 mg is the total amount per bottle
- Whether it is extract weight
- Whether it is a raw-material equivalent
- Whether the product contains approximately 60 grams
- Whether all markets use the same bottle size
Do not state that a user applies 1,000 mg of placenta at each dose or each day.
What Placenta Evidence Exists?
Placenta extracts have shown potential hair-related activity in:
- Dermal papilla cell studies
- Mouse models
- Small human formulation studies
A human study compared a cow-placenta extract lotion with minoxidil 2% in women with pattern hair loss. Other studies have examined human, cow, porcine or goat placenta extracts using different extraction methods and delivery systems.
Those findings provide biological plausibility.
They do not prove that horse placenta extract in 7HP produces the same effect because the following differ:
- Species
- Extraction method
- Concentration
- Molecular profile
- Vehicle
- Applied dose
- Treatment population
- Co-active ingredients
Horse Placenta Is Not Direct Nutrition for the Follicle
Topical application is not equivalent to eating protein, vitamins or minerals.
For a placenta-derived peptide to influence living follicular tissue, it would need to:
- Remain stable inside the bottle.
- Survive the solvent system.
- Leave the vehicle after application.
- Cross or enter the scalp barrier.
- Reach the relevant follicular structure.
- Remain biologically active.
- Be present in a sufficient amount.
The public 7HP information does not provide this delivery data.
Use:
Horse placenta is included as a protein-, peptide- and growth-factor-support ingredient.
Do not use:
Horse placenta directly feeds every follicle.
Animal Source, Allergy and Ethical Verification
Because horse placenta is animal derived, the product documentation should clarify:
- Species confirmation
- Country of origin
- Collection method
- Processing method
- Viral screening
- Microbiological testing
- Heavy-metal testing
- Residual protein profile
- Growth-factor standardisation
- Allergen warning
- Halal-certification status
- Batch traceability
Do not label 7HP:
- Vegan
- Cruelty free
- Halal certified
- Allergy free
- Ethically sourced
without finished-product documentation.
Oxytocin 0.1%: The Hidden Fourth Active
Oxytocin is a peptide hormone involved in several reproductive, behavioural and local tissue-signalling processes.
Research published in 2023 found that oxytocin increased hair-growth-related markers in human dermal papilla cells and promoted hair-peg-like sprouting in laboratory hair-follicle organoids.
A 2026 study further reported that human hair-follicle outer-root-sheath cells can produce oxytocin and that oxytocin signalling may support dermal papilla activity and outer-root-sheath stem-cell proliferation.
These findings strengthen the biological rationale.
They do not prove clinical efficacy from topical 7HP.
Why Laboratory Oxytocin Evidence Is Not a Clinical Result
The oxytocin studies do not establish that 7HP:
- Delivers oxytocin to the lower follicle
- Keeps oxytocin stable in ethanol
- Produces visible scalp regrowth
- Improves hair density in patients
- Reduces shedding
- Treats androgenetic alopecia
- Changes systemic oxytocin levels
- Improves emotional wellbeing
A related laboratory paper notes that oxytocin’s relatively large molecular size and rapid degradation create challenges for prolonged topical scalp administration.
That concern is directly relevant to a topical formula.
Does Topical Oxytocin Reduce Stress?
The product categorises 7HP as a “stress reducer,” but no finished-product trial is shown demonstrating that scalp application:
- Reduces anxiety
- Lowers validated stress scores
- Improves confidence
- Improves social bonding
- Changes central nervous system activity
- Treats stress-related telogen effluvium
Oxytocin’s established medical uses relate primarily to obstetric care, not topical treatment of hair loss or psychological stress.
Use:
Oxytocin is included for an experimental local follicular-signalling rationale.
Do not use:
7HP reduces emotional stress through oxytocin.
Comparing the Four Ingredients
For buyers looking for 7HP ingredients explained by evidence strength, the four actives should not be treated as clinically equivalent.
| Ingredient | Main proposed role | Evidence strength | Main limitation |
| Minoxidil 7% | Follicular growth stimulation | Strong minoxidil evidence; limited exact 7% evidence | Higher strength not automatically superior |
| Dutasteride 0.1% | DHT-pathway inhibition | Established pharmacology; emerging topical trials | Exact 7HP systemic exposure unknown |
| Horse Placenta 1.67% | Peptide and growth-factor support | Laboratory and limited formulation evidence | Different species and delivery systems |
| Oxytocin 0.1% | Experimental follicular signalling | Cell and organoid evidence | No established human topical clinical result |
This evidence ranking should remain visible in the article.
Does Combining Four Actives Prove Synergy?
No.
A combination may be scientifically rational without having proven synergy.
To establish synergy, a controlled trial would need groups such as:
- Vehicle alone
- Minoxidil 7% alone
- Dutasteride 0.1% alone
- Minoxidil plus dutasteride
- Minoxidil plus placenta
- Minoxidil plus oxytocin
- All four actives together
The reviewed pages do not present this research.
Do not claim that:
- Four ingredients multiply results
- 7HP attacks every cause of hair loss
- Horse placenta makes dutasteride safer
- Oxytocin makes minoxidil work faster
- The four ingredients guarantee regrowth
- The formula is superior because it contains more actives

Testimonials and before-and-after photographs
The current evidence position is:
- Minoxidil has strong established evidence at standard strengths.
- A specific topical dutasteride solution has phase II clinical evidence.
- Placenta-extract evidence is indirect and species-specific.
- Oxytocin evidence is preclinical.
- No exact 7HP randomised trial was presented publicly.
- No 7HP pharmacokinetic study was presented.
- No current customer reviews are shown on the UAE product listing.
Propylene Glycol and Ethanol
The official inactive formula includes propylene glycol and ethanol.
These ingredients may help:
- Solubilise active ingredients
- Maintain formula consistency
- Support topical delivery
- Speed drying
They may also contribute to:
- Dryness
- Burning
- Itching
- Scaling
- Redness
- Contact dermatitis
- Irritation
The product should not be marketed as universally non-irritating.
Peppermint Oil, Menthol and African Pepper Extract
The formula also contains peppermint oil, menthol and African pepper extract.
These ingredients may produce:
- Cooling
- Tingling
- Warming
- Sensory stimulation
- Fragrance
A sensory feeling does not prove:
- Better absorption
- Increased hair growth
- Greater blood flow
- Successful DHT reduction
- Treatment efficacy
Tingling may also be a sign of irritation.
Is 7HP a Nutritional Supplement?
No, not in the ordinary meaning of that term.
7HP is applied externally to the scalp and contains pharmaceutical active ingredients.
The “nutritional supplement” classification shown on the product page appears inappropriate or misleading.
A topical horse-placenta extract does not convert the entire formula into an oral nutritional supplement.
The page should classify it according to its verified UAE regulatory status.
Is 7HP FDA Approved?
The manufacturer states that Regrowth Labs products are manufactured in the United States and supplied exclusively to international markets. They are not available for sale or distribution within the United States.
FDA registration of a facility does not mean FDA approval of 7HP.
Do not state:
- FDA-approved 7HP
- FDA-approved topical dutasteride formula
- FDA-certified hair regrowth treatment
- Approved for moderate-to-severe hair loss in the United States
The product’s UAE or international regulatory status should be separately verified.
Who May Research 7HP?
7HP may be researched by an adult man who:
- Has gradual pattern-related thinning
- Has been assessed for androgenetic alopecia
- Has reviewed standard 5% minoxidil
- Is considering a minoxidil-dutasteride combination
- Understands topical dutasteride is non-standard or off-label in many markets
- Has reviewed sexual and psychiatric risks
- Can follow a twice-daily routine
- Can prevent household transfer
- Understands the experimental nature of placenta and oxytocin
- Has realistic expectations
This is a potential research profile—not a prescription.
Who Should Not Self-Select 7HP?
Medical assessment is particularly important where:
- Hair loss is sudden
- Hair loss is patchy
- The cause is unknown
- The scalp is painful or inflamed
- There are sores, crusts or discharge
- Smooth or scarred areas are present
- Hair loss affects a child
- The user is under 18
- The user is a woman
- Pregnancy exposure is possible
- Heart disease is present
- Blood-pressure-lowering medicines are used
- There is a history of depression or suicidal thoughts
- Sexual or fertility concerns are present
- Another dutasteride or minoxidil product is already used
- There is a significant animal-protein allergy
The broader diagnostic pathway is explained in the Complete Hair-Loss Action Plan.
Hairline Versus Crown Use
The official manufacturer states that 7HP is formulated for the vertex scalp. The UAE product copy additionally targets receding hairlines.
That discrepancy should be corrected before the article promises frontal use.
Until the physical label is verified:
- Do not guarantee temple regrowth.
- Do not guarantee restoration of a receded hairline.
- Do not add extra sprays for a second treatment area.
- Avoid forehead run-off.
- Keep the formula away from eyebrows and eyes.
The article can state:
The current official indication clearly names the vertex, while the UAE marketing copy also mentions the hairline; the physical market-specific label should determine the intended zones.
Confirmed Application Framework
Based on the current product page:
- Apply five sprays to the thinning scalp.
- Repeat twice daily.
- Massage for two to four minutes.
- Do not apply more than directed.
- Wash hands after application.
- Prevent contact with the eyes.
- Keep the product away from children.
- Stop and seek medical advice after chest pain or rapid heartbeat.
Based on the general Regrowth Labs FAQ, the brand’s leave-in products are normally applied to a dry scalp and left for at least four hours. These details must be confirmed against the physical 7HP label before publication.
Does Five Sprays Equal One Millilitre?
The general manufacturer FAQ states “1 mL / 5 sprays per dose.”
The exact 7HP product page only states five sprays.
Before converting sprays into an active dose, verify:
- Spray output from the actual bottle
- Whether the first pump requires priming
- Whether every pump delivers equal volume
- Whether five sprays consistently equal one millilitre
- Whether the physical 7HP label confirms the equivalence
Do not calculate daily milligrams from the FAQ alone.
What Should Happen After a Missed Application?
The current 7HP page does not provide a missed-application rule.
Do not:
- Use ten sprays at the next application
- Apply two doses together
- Shorten the interval independently
- Increase the amount later in the day
Resume the verified schedule unless the prescriber or label advises otherwise.
Can 7HP Be Combined With Other Minoxidil Products?
7HP already contains minoxidil 7%.
Combining it with:
- Minoxidil foam
- Minoxidil solution
- Oral minoxidil
- 5HP
- FR10
- FR12
- FR15
- FR16
- M7α
may increase total minoxidil exposure.
Additional minoxidil should not be added casually.
Can 7HP Be Combined With Finasteride or Dutasteride?
7HP already contains dutasteride 0.1%.
Combining it with:
- Oral dutasteride
- D5a
- Oral finasteride
- Topical finasteride
- FIN25
- FR12
- FR16
may increase total 5-alpha-reductase-inhibitor exposure and make adverse effects harder to identify.
The broader medicine comparison belongs in the Finasteride vs Dutasteride guide.
5HP Versus 7HP
Both official active panels currently list:
- Dutasteride 0.1%
- Horse Placenta Extract 1.67%
- Oxytocin 0.1%
The main disclosed active difference is:
| Product | Minoxidil concentration |
| 5HP | 5% w/w |
| 7HP | 7% w/w |
The products should not be described as entirely different multi-active systems when their disclosed panels otherwise appear identical.
The physical labels should confirm whether:
- Both genuinely contain oxytocin
- Both genuinely contain dutasteride
- Both use the same inactive base
- Only minoxidil concentration differs
- The intended treatment stage differs
A dedicated comparison article should own the full 5HP-versus-7HP decision.
D5a Versus 7HP
D5a follows a different formulation strategy:
- D5a publicly lists dutasteride 0.5% with azelaic acid.
- 7HP lists dutasteride 0.1%, minoxidil 7%, horse placenta and oxytocin.
D5a places greater emphasis on concentrated topical DHT inhibition.
7HP combines a lower stated dutasteride concentration with minoxidil and experimental biological-support actives.
Neither should be chosen based on percentages alone.
Microneedling and Damaged Scalp
Do not apply 7HP immediately after microneedling without explicit medical guidance.
Damaged skin may change exposure to:
- Minoxidil
- Dutasteride
- Oxytocin
- Placenta proteins
- Propylene glycol
- Ethanol
- Menthol
- Pepper extract
Avoid application to:
- Open cuts
- Bleeding skin
- Active dermatitis
- Infected scalp
- Painful inflammation
- Severe sunburn
UAE Routine Considerations
Heat and Sweat
Applying immediately before exercise or outdoor activity may cause run-off before the formula dries.
Allow the treatment to dry before:
- Exercising
- Wearing a helmet
- Wearing tight headwear
- Lying down
Showering
The brand FAQ says leave-in treatments generally remain on the scalp for at least four hours before washing. Confirm that this appears on the current 7HP physical label.
Headwear
Caps, helmets and ghutras may absorb wet treatment.
This can:
- Remove part of the dose
- Create household-transfer surfaces
- Increase facial run-off
- Increase residue
Styling Products
Apply the medicine to visible scalp rather than coating hair fibres, wax or oil.
Avoid layering several scalp products before 7HP has dried.
Storage in Dubai and the UAE
The manufacturer states:
- Store at 20°C to 25°C
- Keep the container closed
- Slight darkening may occur over time without necessarily changing expected performance
Do not store 7HP:
- Inside a parked vehicle
- On a balcony
- On a sunny windowsill
- Near a cooker
- In an unlabelled bottle
- With the nozzle left open
- Where children can reach it
Seek supplier clarification after:
- Significant separation
- Heavy precipitation
- Leakage
- Broken seal
- Missing batch information
- Missing expiry information
- Major texture or odour change
What Results Should Buyers Expect?
The manufacturer says results may become noticeable in as little as two months but are more often noticed around four months, with individual variation.
This is manufacturer guidance, not an independent 7HP randomised-trial result.
Do not promise:
- Visible regrowth by month two
- Guaranteed crown filling
- Guaranteed hairline restoration
- A response in every user
- Permanent regrowth
- Better results than 5%
- Stress reduction
- Improved confidence
- Proven four-active synergy
- Initial shedding as proof of success
- Faster results from extra sprays
Tracking Results and Safety
Take standardised photographs approximately every four weeks:
- Straight frontal hairline
- Left temple
- Right temple
- Mid-scalp
- Crown
Record:
- Start date
- Number of sprays
- Missed applications
- Scalp irritation
- Dryness
- Burning
- Chest symptoms
- Palpitations
- Dizziness
- Swelling
- Sexual symptoms
- Mood changes
- Other minoxidil products
- Other DHT inhibitors
- Microneedling
- Haircuts
Photographs can document appearance.
They cannot prove:
- Serum dutasteride exposure
- DHT reduction
- Oxytocin penetration
- Horse-placenta activity
- Four-active synergy
- Product authenticity

Frequently Asked Questions
What are the ingredients in 7HP?
The current official active panel lists minoxidil 7% w/w, horse placenta extract 1.67% w/w, dutasteride 0.1% w/w and oxytocin 0.1% w/w.
Does 7HP contain oxytocin?
Yes. Oxytocin 0.1% w/w is listed in the active-ingredient panel, even though it is omitted from the product title.
Why does the title show only three ingredients?
The public page does not explain why oxytocin is omitted from the title. The physical product label should be checked.
Does 7HP contain minoxidil 7%?
Yes. The official formula lists Minoxidil USP 7% w/w.
Is minoxidil 7% proven better than 5%?
No direct evidence reviewed here establishes that 7% is clinically superior to 5%. Higher concentration does not automatically mean better outcomes.
Does 7HP contain dutasteride?
Yes. Dutasteride 0.1% w/w is listed.
Does dutasteride inhibit type III 5-alpha-reductase?
Authoritative clinical descriptions identify dutasteride as inhibiting type I and type II 5-alpha-reductase. The product’s type III wording should be corrected.
Is topical dutasteride approved for hair loss?
Topical dutasteride is an emerging and formulation-specific treatment approach. The exact 7HP product should not be described as an FDA-approved topical dutasteride medicine.
Has topical dutasteride been studied?
Yes. A 2025 phase II study evaluated specific 0.01%, 0.02% and 0.05% topical solutions. Those findings cannot be copied directly onto 7HP 0.1%.
Does topical dutasteride have zero systemic absorption?
No. A topical study reported modest serum hormonal changes, and 7HP-specific systemic exposure has not been published.
What does horse placenta 1,000 mg mean?
The title says 1,000 mg, while the ingredient panel states 1.67% w/w. The quantity may represent total bottle content, but the net weight must be confirmed.
Does horse placenta clinically regrow hair?
Placenta extracts have experimental and limited human research, but the exact horse-placenta extract inside 7HP has not been shown publicly to produce confirmed clinical regrowth.
Why is oxytocin used in 7HP?
Laboratory research suggests oxytocin may influence dermal papilla and outer-root-sheath signalling. Its clinical effect in topical 7HP has not been established.
Does oxytocin in 7HP reduce stress?
No product-specific evidence reviewed here proves that scalp application reduces psychological stress or improves confidence.
Are all four ingredients clinically proven?
No. Minoxidil has the strongest evidence. Topical dutasteride has emerging evidence, while placenta and oxytocin are less established.
How many sprays should be applied?
The current product directions state five sprays twice daily.
Do five sprays equal one millilitre?
The general Regrowth Labs FAQ says one millilitre or five sprays per dose, but the physical 7HP applicator should confirm this equivalence.
How long should 7HP stay on the scalp?
The general manufacturer FAQ says leave-in treatments should remain for at least four hours. Confirm that instruction on the physical 7HP label.
Can more sprays improve results?
No. The manufacturer states that using more or applying the product more often will not improve results.
Can 7HP be used on the hairline?
The UAE marketing copy mentions receding hairlines, while the official indication specifically names the vertex. The physical label should resolve the intended zones.
Can women use 7HP?
The official product is intended for men and contains dutasteride. It should not be promoted to women without specialist assessment.
Can pregnant women touch wet 7HP?
Pregnant individuals should avoid applying or contacting wet dutasteride-containing treatment because of potential fetal risk.
Can 7HP cause sexual side effects?
Dutasteride is associated with sexual-function warnings. The frequency from topical 7HP is unknown.
Can 7HP affect mood?
Regulators have added precautionary psychiatric guidance for dutasteride, including depression and suicidal-thought monitoring.
Can 7HP cause cardiovascular symptoms?
Minoxidil-related warning signs include chest pain, rapid heartbeat, dizziness, faintness and swelling. The manufacturer specifically directs users to stop after chest pain or rapid heartbeat.
Can 7HP irritate the scalp?
Yes. The formula contains propylene glycol, ethanol, peppermint oil, menthol and African pepper extract, any of which may contribute to irritation.
Does tingling mean 7HP is working?
No. Tingling may come from menthol, peppermint, pepper extract or irritation. It does not prove treatment efficacy.
Can 7HP be used after microneedling?
Do not apply it to freshly microneedled or damaged scalp without explicit professional guidance.
Can 7HP be combined with minoxidil foam?
It already contains minoxidil 7%. Adding more minoxidil may increase total exposure.
Can 7HP be combined with oral finasteride?
It already contains dutasteride. Combining DHT inhibitors requires medical supervision.
Can 7HP be combined with D5a?
Both products contain dutasteride and should not be combined casually.
How should 7HP be stored in Dubai?
Store at 20°C to 25°C with the container closed. Do not leave it in a parked vehicle or direct sunlight.
Final Perspective
With 7HP ingredients explained in full, the product is a four-active formula even though its commercial title highlights only three ingredients.
Minoxidil 7%
↓
Established medicine at a less-established strength
Dutasteride 0.1%
↓
Potent DHT inhibition with emerging topical evidence
Horse Placenta Extract 1.67%
↓
Biological-support rationale with indirect evidence
Oxytocin 0.1%
↓
Experimental follicular-signalling rationale
The strongest evidence belongs to minoxidil, although 7% should not be assumed better than standard 5%.
Dutasteride provides a credible DHT-targeting pathway, but 7HP’s exact systemic exposure, serum-DHT effect and long-term safety are not publicly shown.
Horse placenta provides a distinctive peptide- and growth-factor formulation concept, but research involving cow, human, porcine or goat placenta cannot automatically validate horse placenta inside 7HP.
Oxytocin is supported by increasingly interesting cell and follicle-organoid research, including 2026 findings involving outer-root-sheath oxytocin production. That remains preclinical evidence rather than proof of visible clinical regrowth from a scalp spray.
The strongest potential buyer fit is an adult man who:
- Has diagnosed androgenetic alopecia
- Has reviewed standard 5% minoxidil
- Has been assessed for dutasteride suitability
- Understands sexual and psychiatric warnings
- Can prevent pregnancy-related transfer
- Understands the experimental nature of placenta and oxytocin
- Can follow the verified five-spray twice-daily routine
- Will not combine overlapping treatments without guidance
- Can monitor cardiovascular and scalp symptoms
- Has realistic expectations
The responsible conclusion is:
7HP combines minoxidil 7%, dutasteride 0.1%, horse placenta extract 1.67% and oxytocin 0.1%. The formula addresses several plausible pathways, but its four ingredients do not have equal evidence, and the exact finished product requires independent clinical, pharmacokinetic and dose-verification data before it can be described as superior or comprehensively proven.
