In brief:
- Four references structure the offer of food supplements for hair loss: Biocyte Kératine Forte 900 mg, Arkopharma’s Forcapil Anti-chute, Luxéol Chute de cheveux réactionnelle and Phyto’s Phytophanère, with displayed prices from 0.19 to 1.68 euro a day.
- Biocyte combines 900 mg of hydrolysed keratin with three amino acids, horsetail and rocket, and details its doses for 3 capsules a day: biotin 312 µg, copper 1.49 mg, zinc 1.5 mg.
- The daily biotin dose ranges from 25 µg for Luxéol to 450 µg for Forcapil, with 150 µg for Phytophanère and 312 µg for Biocyte. Only biotin, zinc, selenium and copper carry an authorised claim on hair.
- Each formula has its own rhythm: one intake a day (Forcapil, Luxéol), two (Phytophanère) or three (Biocyte). Hair loss that lasts more than three months calls for medical advice.
Choosing the best food supplement for hair loss means comparing formulas, doses and an intake rhythm, far more than looking for a single product. This comparison brings together four references sold in France, presented through their strengths, with the doses published by the brands and the cost per day of each course.

Hair loss: when a supplement makes sense
Hair follows a growth, transition and rest cycle, at the end of which it falls out and makes way for a new one. More marked shedding often appears during seasonal changes, after a period of stress or fatigue, or after hormonal upheaval, as the brands in this comparison describe. A food supplement is then considered as a contribution of nutrients that take part in hair structure, within a varied diet.
The most common situations
- Seasonal hair loss: it is mostly seen in autumn and spring, which explains why courses are advised at those two times.
- Hair loss linked to stress or fatigue: it often shows up a few weeks after the event. Stress is also tied to sleep quality, as the comparison of natural food supplements for sleep explains.
- Persistent hair loss, with bare patches: it calls for medical advice and a check-up, as a supplement does not replace a diagnosis.
What European regulation allows to be said
Regulation (EU) No 432/2012 sets the list of authorised health claims. For hair, four nutrients have an authorised wording, shown in the following table.
| Nutrient | Authorised claim | References that contain it |
|---|---|---|
| Biotin | Contributes to the maintenance of normal hair | Biocyte, Forcapil, Luxéol, Phytophanère |
| Zinc | Contributes to the maintenance of normal hair | Biocyte, Forcapil, Luxéol, Phytophanère |
| Selenium | Contributes to the maintenance of normal hair | Luxéol |
| Copper | Contributes to the maintenance of normal hair pigmentation | Biocyte, Forcapil |
| Vitamin B6 | Contributes to normal cysteine synthesis | Biocyte, Forcapil, Luxéol, Phytophanère |
Keratin, L-cystine added as an ingredient and plant extracts such as horsetail, rocket or Montpellier maidenhair have no authorised claim on hair: brands present them as formulation elements. This helps when reading a label: only the presence of a nutrient from the list entitles a product to the matching claim.
How to choose a hair supplement
Read the biotin and zinc dose
The nutrient reference value for biotin is 50 µg a day. The four references compared range from 25 µg to 450 µg, or from 50% to 900% of that value. For zinc, the reference value is 10 mg: Forcapil provides 10 mg, Luxéol 5 mg, Biocyte 1.5 mg. A higher dose does not mean a different promise, since the authorised claim is the same.
Look at the intake rhythm
One intake a day (Forcapil, Luxéol), two (Phytophanère) or three (Biocyte): the rhythm matters over several months. Biocyte allows the 3 capsules to be split into one or several intakes, with a large glass of water, preferably in the morning. Luxéol specifies that the capsule can be opened and mixed into yoghurt or compote.
Take the length of the course into account
The hair cycle is slow: all the brands advise regular intake over several weeks. Forcapil and Luxéol recommend 3 months, Phytophanère two 3-month courses a year and Biocyte a course of one month minimum, to be renewed.
Think about precautions for use
Each leaflet has its own precautions. The supplements compared are not recommended during pregnancy and breastfeeding (Forcapil, Luxéol, Biocyte), and Phytophanère invites pregnant and breastfeeding women to ask a health professional for advice. Luxéol and Forcapil also flag that advice should be sought for anyone on antidiabetic treatment. Biocyte does not recommend its product in case of cardiac or oedematous renal insufficiency and under 12 years of age.
Biotin deserves particular attention. At high doses, it can skew some laboratory tests, notably those of thyroid function, as stated by the ANSM in its information on biotin interference. Report any supplement containing biotin to the laboratory before a blood test.
Biocyte Kératine Forte 900 mg: a hydrolysed keratin formula
Biocyte is a French food supplement laboratory, which devotes part of its range to hair. Its Kératine Forte 900 mg relies on the K-AMINE+ complex, which combines 900 mg of hydrolysed keratin with three amino acids that make up keratin: cysteine, serine and methionine, at 50 mg each. Rocket extract (100 mg) and horsetail extract (12.5 mg) complete the formula.
Key characteristics
- Detailed doses: for 3 capsules, the product page publishes biotin (312 µg, or 624% of the NRV), copper (1.49 mg, or 149%), vitamin B6 (2.1 mg, or 150%) and zinc (1.5 mg, or 15%), as well as vitamins B3 and B5.
- Plant-based capsules, stated to be allergen free, to be taken preferably in the morning with a large glass of water.
- A 2-month programme at 67.00 euros, instead of 99.00 euros, or 1.12 euro a day, in addition to the box of 60 capsules at 33.50 euros for 20 days.
- A real-life satisfaction study carried out in 2024 by a research institute on 50 women over 2 months: 94% of participants report stronger hair and 92% more resistant hair.
- A hair range that also includes Kératine Forte 500 mg, Kératine Max powder, a keratin and hyaluronic acid combination and gummies.
This formula suits readers who are looking for a combination of keratin and amino acids with published doses, as well as a two-month programme. The course is considered within a varied diet, as the product page points out.
The other solutions and their strengths
Arkopharma’s Forcapil Anti-chute
Arkopharma is a food supplement laboratory. Its Forcapil Anti-chute reference comes as one tablet a day, taken at breakfast with a large glass of water, from the age of 15. The formula combines 150 mg of Venus hair fern (maidenhair) and 45 mg of horsetail with 400 mg of L-cystine and 100 mg of L-methionine, together with vitamins B5, B6, B8 and B9, vitamin D3, 10 mg of zinc and 1 mg of copper. The biotin dose, 450 µg, is the highest of the comparison. The box of 90 tablets at 33.00 euros covers 3 months, or 0.37 euro a day, and the brand advises a course of 3 months minimum, renewable at each change of season.
Luxéol Chute de cheveux réactionnelle
Luxéol offers distinct references depending on the type of hair loss, progressive or reactive. The reactive version, intended for hair loss linked to stress, fatigue or seasonal changes, combines in a daily capsule 150 mg of Montpellier maidenhair, 30 mg of California poppy, 30 mg of horsetail, 50 mg of L-cystine, 50 mg of L-methionine, 5 mg of zinc, 25 µg of biotin, 11 µg of selenium and vitamin B6. It is the only formula in the comparison to contain selenium, a nutrient that also carries the claim on the maintenance of normal hair. The recommended programme lasts 3 months, with a box of 90 capsules at 49.80 euros. The brand ran a usage test on 120 people over 3 months.
Phyto’s Phytophanère
Phyto is a hair care brand that offers Phytophanère as capsules, effervescent tablets, serum and ampoules. The Duo pack of 240 capsules, displayed at 23.20 euros instead of 29.00 euros, covers 4 months at 2 capsules a day, or 0.19 euro a day, the lowest price per day in the comparison. Its formula combines 150 µg of biotin and zinc bisglycinate with vitamins B2, B5, B6, C and E, acerola, carrot oil macerate, brewer’s yeast and plant oils. Retailers advise two 3-month courses a year, in autumn and spring.
The same dose logic is found in the other formats of the category: the comparison of the best hair growth gummies details the biotin dose per gummy and the cost of a three-month course.
Which supplement for which profile?
For seasonal hair loss in autumn or spring
Forcapil Anti-chute and Phytophanère offer long formats, of 3 and 4 months, which cover a full course at each change of season. Biocyte offers a 2-month programme, which matches the length of its satisfaction study.
For hair loss that follows a period of stress or fatigue
Luxéol Chute de cheveux réactionnelle combines, in its formula, California poppy and selenium with Montpellier maidenhair and sulfur amino acids. It is taken as one capsule a day over 3 months.
For a hydrolysed keratin formula
Biocyte Kératine Forte 900 mg is the formula in the comparison built around hydrolysed keratin, with three amino acids and published doses for each ingredient. For readers interested in other structural proteins, the comparison of the best marine collagen presents the collagen doses of the brands.
For a single intake a day
Forcapil Anti-chute and Luxéol Chute de cheveux réactionnelle are taken in a single daily gesture, one tablet or one capsule, with no splitting over the day.
For a reduced budget per day
Phytophanère Duo displays the lowest price per day in the comparison, at 0.19 euro, followed by Forcapil Anti-chute at 0.37 euro.
Practical advice before choosing
- Read the full composition and compare the biotin and zinc doses with the nutrient reference values, rather than the range names.
- Bring the price down to a day: the duration covered by a box varies from 20 days to 4 months from one reference to another.
- Follow the daily dose shown on the box and do not combine several supplements containing biotin or zinc.
- Tell the laboratory about biotin intake before a blood test.
- Ask a doctor or a pharmacist for advice in case of pregnancy, breastfeeding, ongoing treatment or hair loss that is setting in.
- Consult a doctor if hair loss lasts more than three months, if bare patches appear or if there are associated signs such as intense fatigue.
