Folliboost Hair Growth Serum review: ingredients, evidence and value

Published 20 October 2026

Folliboost Hair Growth Serum by Tricho Labs combines botanical extracts, biotin and peppermint oil in a leave-in formula marketed for thicker, fuller-looking hair.

Its headline ingredients include AnaGain and Baicapil, two branded botanical complexes used in products targeting thinning hair. But how convincing is the evidence, and is the three-pack worth its premium price?

Our verdict: Folliboost contains ingredients with some supporting research, but we could not verify strong clinical evidence that the finished serum reliably reverses hair loss. It is worth approaching with realistic expectations, especially when buying several bottles upfront.

Folliboost at a glance

What is Folliboost Hair Growth Serum?

Folliboost is a topical serum applied directly to the scalp and left in rather than rinsed out. Tricho Labs markets it to people seeking improvements in hair thickness, fullness and visible density.

The formula brings together botanical complexes and ingredients commonly associated with hair care. Its marketing emphasises a lightweight feel and peppermint scent.

However, improving the appearance of existing hair and producing new growth are different outcomes.

Hair can look fuller because of changes in texture, styling or condition. Demonstrating actual regrowth requires more objective evidence, such as standardised hair counts or density measurements over time.

That distinction matters when assessing Folliboost’s claims.

What is in Folliboost?

The listing supplied for this review highlights AnaGain, Baicapil, biotin, peppermint oil, D-panthenol and arginine.

This is a selection of promoted ingredients, rather than a verified complete ingredient list. Check the full label on the product you receive, as formulations and listings can change.

AnaGain: pea sprout extract

AnaGain is a branded pea sprout extract marketed for use in products targeting hair shedding and thinning.

A published investigation included a small topical study involving 10 volunteers who applied a preparation containing 2% AnaGain twice daily for two weeks. That part of the research examined biological markers associated with hair growth.

This is useful preliminary research, but it does not establish that Folliboost produces substantial visible regrowth.

There are several unanswered questions:

• Does Folliboost contain the concentration used in the research?
• Does the finished formula perform in the same way?
• Are any changes large enough to be noticeable?
• Do results persist with continued use?

The ingredient has a research basis, but its inclusion does not guarantee a particular outcome from this serum.

Baicapil: a botanical complex

Baicapil is a branded complex associated with soya, wheat and Chinese skullcap extracts. Its supplier markets it for reducing hair loss and improving density.

Supplier research can help explain the rationale behind an ingredient. However, it should be distinguished from independent testing of a finished retail product.

We could not verify the concentration of Baicapil in the Folliboost listing supplied. This makes it difficult to compare the serum directly with research formulations.

The presence of Baicapil is a reason to investigate the formula further, rather than proof that the serum will reverse thinning.

Biotin

Biotin is widely promoted in hair care, and it is one of Folliboost’s most prominent ingredients.

However, the presence of biotin in a topical serum does not establish that the product increases hair density.

Research relevant to that claim would need to assess topical application, the concentration used and the finished formulation. Evidence about dietary biotin or supplements should not automatically be applied to a scalp serum.

We could not establish that Folliboost’s topical biotin independently delivers measurable regrowth.

Peppermint oil

Peppermint oil contributes to the serum’s advertised scent and is often discussed in relation to hair growth.

A frequently cited 2014 study reported hair growth effects from topical peppermint oil in mice. It was not a human clinical trial and did not test Folliboost.

That distinction prevents several misleading conclusions. The study does not prove that Folliboost regrows human hair or that peppermint oil is more effective than minoxidil in people.

Likewise, a cooling or tingling sensation should not be interpreted as evidence of new growth.

D-panthenol and arginine

The supplied listing also highlights D-panthenol, a form of provitamin B5, and arginine.

These ingredients contribute to the formulation, but their presence alone does not demonstrate that the serum reverses hair loss.

We did not identify finished-product evidence establishing their individual contribution to Folliboost’s advertised growth results.

Does Folliboost actually work?

The evidence reviewed does not establish reliable hair regrowth from the finished Folliboost serum.

Some of its ingredients have supporting research, but ingredient evidence and finished-product evidence are different.

The outcome of a serum depends on more than its headline ingredients. Concentrations, formulation, application, scalp tolerance and the underlying cause of thinning can all affect the result.

A persuasive clinical trial would explain:

• The exact product tested.
• The number of participants.
• Their type of hair loss.
• The comparison or placebo used.
• Changes in objective hair measurements.
• Reported side effects.
• Study funding and conflicts of interest.

During this review, we did not identify a publicly accessible, peer-reviewed clinical trial establishing the effectiveness of the finished Folliboost serum.

That describes the evidence we found. It does not establish that no other research exists.

How to use Folliboost Hair Growth Serum

The manufacturer describes a twice-daily routine:

1. Apply one to three drops to each target area of the scalp.
2. Massage gently with your fingertips.
3. Leave the serum in rather than rinsing it out.

Follow the instructions on your own bottle if they differ from online guidance. Do not assume that using more will produce faster results.

How to track any changes

Take photographs before starting, then repeat them monthly using:

• The same lighting.
• The same hair parting.
• The same camera distance.
• Similar styling.
• Dry hair in each photograph.

This helps reduce misleading differences caused by lighting, wet hair or a changed parting.

Record any other changes to your routine too. Starting several products at once makes it difficult to know what caused an improvement or irritation.

How long does Folliboost take to work?

Tricho Labs recommends using the serum for at least three months when assessing results.

This is the manufacturer’s suggested timeframe, rather than a guarantee of regrowth within 90 days.

It is also not possible to confirm how long a bottle will last from the pack size alone. Consumption depends on the amount applied and the area covered.

Avoid assuming that a three-pack automatically provides exactly three months of treatment.

Folliboost price: is the three-pack good value?

The Amazon listing supplied for this review showed a price of £168.13 for three bottles.

That works out at approximately £56.04 per bottle, assuming three equally sized bottles are included.

Prices and sellers can change, so check the current offer before ordering.

Check the unit-price calculation

The supplied listing displayed a unit price of approximately £284.26 per 100 ml.

However, if the pack contains three bottles of 2 US fluid ounces each, the combined volume would be approximately 177 ml. On that assumption, £168.13 works out at roughly £94.75 per 100 ml.

The displayed unit price appears consistent with dividing the total pack price by the volume of one bottle.

This suggests a possible mismatch between the pack quantity and the volume used in the listing’s calculation. Confirm the bottle count and individual volume before comparing prices.

Is it worth buying three bottles at once?

A multi-pack may suit an existing user who already knows the formula agrees with their scalp.

For a first-time buyer, it creates a larger upfront commitment before establishing suitability or seeing any benefit.

If a smaller pack is available, compare its total cost, seller and return conditions before choosing.

What do Amazon customer ratings tell us?

The listing supplied for this review showed 4.2 out of 5 stars from 46 reviews.

This is a snapshot of the supplied listing, rather than a live rating. We have not independently analysed those reviews or verified whether they relate to the same pack size.

Customer feedback may help answer practical questions about packaging, scent and application.

It is less reliable as evidence of hair regrowth because reviews may not account for:

• Different causes of thinning.
• Other products used at the same time.
• Natural changes in shedding.
• Differences in photography.
• The length of time the product was used.

The customer rating should therefore be treated as shopping context rather than clinical evidence.

Folliboost pros and cons

Who might consider Folliboost?

Folliboost may interest someone who wants a botanical scalp serum and understands the uncertainty around its growth claims.

It is more reasonable to consider it when:

• You have realistic expectations.
• You can maintain the application routine.
• The cost is comfortable.
• You have checked the complete ingredients.
• You understand the seller’s return conditions.

It is a less convincing purchase if you expect guaranteed regrowth, want rapid results or are relying on the serum to identify and address the cause of ongoing hair loss.

Folliboost versus minoxidil

Folliboost and minoxidil should not be treated as equivalent products.

The NHS identifies minoxidil as a treatment for male-pattern and female-pattern hair loss. It also explains that these treatments do not work for everyone and generally only work while they are being used.

If your priority is treating progressive thinning, understanding its cause is a more useful first step than choosing solely by marketing claims.

A GP or pharmacist can help explain appropriate options. The NHS recommends understanding the cause of hair loss before approaching a commercial hair clinic.

What to check before buying

Full ingredients

Check the complete product label. Promotional graphics showing selected ingredients do not describe the entire formula.

Seller and pack size

The supplied offer named Fabax Dist. as the seller. Confirm the current seller, number of bottles and individual bottle volume at checkout.

Returns and guarantees

Check the conditions applying to the specific Amazon order, including whether opened products can be returned.

Do not assume that a guarantee advertised on the manufacturer’s website applies to a third-party purchase.

Colour compatibility and certifications

We could not verify that the finished serum is colour-safe, vegan or paraben-free.

Properties or certifications associated with one ingredient do not automatically apply to the whole formula.

Frequently asked questions

Is Folliboost proven to regrow hair?

We did not identify robust published clinical evidence establishing regrowth from the finished Folliboost serum. Some promoted ingredients have supporting research, but that does not prove the retail product produces the same results.

Does Folliboost contain minoxidil?

Minoxidil was not named among the highlighted ingredients supplied for this review. Check the complete label to confirm the formulation you are buying.

How often should you apply Folliboost?

The manufacturer describes twice-daily application. Apply the amount directed on your bottle, massage gently and leave it in.

How long should you use Folliboost before assessing results?

The manufacturer recommends at least three months. This is an assessment period, rather than a guaranteed timeframe for regrowth.

Does Folliboost make hair greasy?

The brand markets the serum as lightweight and non-greasy. We have not independently tested this claim, and the amount applied may affect how it feels.

Can Folliboost be used on coloured hair?

We could not confirm colour compatibility for the specific formulation reviewed. Ask the manufacturer before use if preserving a recent colour treatment is important.

Is Folliboost vegan or paraben-free?

We could not verify those claims for the finished serum. Check the full packaging and current manufacturer information.

How long does one bottle last?

There is insufficient verified information to give a reliable duration. It depends on the amount applied and the area covered.

Is the three-pack worth £168.13?

At approximately £56.04 per bottle, it is a significant purchase. Its value depends on suitability and results, which remain uncertain. First-time buyers should compare smaller packs and check return conditions.

Final verdict: should you buy Folliboost?

Folliboost brings together botanical ingredients that have attracted hair-growth research, but the finished product’s effectiveness remains uncertain.

AnaGain and Baicapil make the formula worth examining. Peppermint research also attracts attention, although findings in mice should not be presented as proof of human regrowth.

At the supplied £168.13 three-pack price, we would approach the purchase cautiously. Verify the full ingredients, pack volume and return conditions, and keep expectations realistic.

For anyone concerned about ongoing hair loss, understanding the cause should come before a substantial investment in a cosmetic serum.
