Frequently Asked Questions

Keratin works from the inside out: you must give your hair time to renew itself.

After 30 days, hair loss is noticeably reduced. After 90 days, the fiber is visibly denser, shinier, and hair loss can be reduced by up to 46%. This is why we recommend a 3-month consecutive treatment.

Yes, for the most frequent types of hair loss: seasonal shedding, or loss linked to stress, fatigue, a deficiency, or hormonal changes (postpartum, menopause). Keratin strengthens the hair shaft at the root and prevents breakage.

In the event of diagnosed androgenetic alopecia or hair loss linked to medical treatment, please consult a dermatologist: keratin can support a treatment plan, but it is not a substitute for one.

Its primary action is to slow down hair loss and strengthen the fiber: hair that breaks less appears longer and fuller very quickly.

To actively stimulate growth, combine it with the Growth Kit (shampoo, mask, gummies): the keratin acts on strength, while the Kit works on growth and the scalp.

Yes. Keratin is the main component of both nails and hair. After a 90-day treatment, nails are twice as strong and split less.

The benefits gained last for several weeks, then gradually fade as the hair renews itself. You can continue the treatments without interruption or start a new 3-month treatment at the change of each season.

1 tablet per day, with a glass of water, at the time of day that suits you best. It is best to take it at the same time every day so you don't forget, for example with breakfast.

One box contains 30 tablets, or 1 month's supply. For a full 3-month course, allow for 3 boxes.

Yes. Keratin is a natural nutrient; it can be taken continuously without habituation. Many of our clients take it year-round and boost their results with the Growth Kit during seasonal changes.

Yes, and it is actually the ideal combination: keratin acts on the strength of the fiber, the gummies provide zinc and biotin for growth, and the shampoo and mask treat the scalp.

Keratin contains neither vitamins nor minerals, so there is no risk of overdose when combining it with the gummies.

Simply resume the following day, without doubling the dose. A one-time missed dose has no impact on the results of the treatment.

No known contraindications for healthy adults. For adults only. As a precaution, consult your doctor if you are pregnant, nursing, undergoing medical treatment, or suffering from a medical condition.

Food supplement: does not replace a varied and balanced diet and a healthy lifestyle.

It is a naturally sourced keratin, made soluble and assimilable through a patented process. While conventional keratin is inert and cannot cross the digestive barrier, Cynatine® HNS is bioavailable: it delivers the sulfur-containing amino acids that make up hair directly to the hair bulb.

Each tablet contains 500 mg, the dosage used in clinical studies.

Because it is one of the few keratins to have been clinically tested for oral use: up to a 46% reduction in hair loss and nails twice as strong after 90 days, with 100% of testers satisfied.

We have chosen a single, highly dosed active ingredient rather than a diluted blend of dozens of ingredients.

No: keratin is a protein of animal origin, obtained from sheep's wool, without slaughter. It is suitable for vegetarians but not for vegans.

If you follow a vegan diet, our (vegan) gummies and the shampoo + mask will provide you with a complete alternative.

Hormone-free, sugar-free, no added gluten. The formula contains sulfites (naturally occurring in keratin hydrolysate): if you have a known sensitivity to sulfites, consult your doctor.

Complete composition: Cynatine® HNS (keratin hydrolysate, sulfites) 500 mg, acacia gum, fatty acids, hydroxypropyl methylcellulose, microcrystalline cellulose.

To ensure a precise 500 mg dose of Cynatine® HNS per intake, with no sugar or flavoring. The tablet is small, flavorless, and stores perfectly: 1 per day, that's all.

Que du bonheur

Shampoing au top, j’ai l’impression que ça fonctionne bien! J’ai pris quelques cms mais je crois aussi que c’est la combinaison avec le masque qui joue: car le masque répare bien et fait les cheveux superstar doux donc moins cassants.
J’aime énormément ce duo, que je rachèterai avec plaisir!
