Je suis ravie du sérum

"Je suis ravie du sérum ! Je vois déjà des progrès alors que ça fait 1 mois et une semaine d’utilisation. J’avais essayé beaucoup de méthodes pour faire repousser les cheveux mais sans vraiment de résultat. Mais là, voir de nouveaux petits cheveux apparaître me remonte le moral et je rachèterai pour pouvoir continuer ma routine et voir les résultats !"

Nanethinie S. (5/5)

J'utilise la routine depuis 2

"J'utilise la routine depuis 2 mois et je suis plutôt satisfaite pour le moment. Le shampooing est top pour les cheveux fins, il apporte du volume sans alourdir. Le sérum ne graisse pas du tout les cheveux, même si je n’ai pas encore de résultats très visibles sur la chute, je note une légère amélioration. J’ai une alopécie androgénétique diagnostiquée récemment, donc je reste patiente. Le casque et le dermastamp sont aussi faciles à utiliser et complètent bien la routine. Je compte poursuivre jusqu’à 6 mois pour voir les résultats sur le long terme. La 1ère photo date de début mars 2026 et la seconde d'il y a quelques jours."

Marine C. (5/5)

Je viens de terminer ma

"Je viens de terminer ma première cure d’un mois. Le sérum est très facile à utiliser et ne laisse pas les cheveux gras, ce qui est vraiment appréciable. Il est encore un peu tôt pour donner un avis définitif, mais j’ai déjà remarqué des repousses au niveau des tempes. Je vais donc poursuivre le traitement avec impatience afin de voir si cette première impression se confirme."

Nathalie (5/5)

Je suis du genre très

"Je suis du genre très sceptique et j’ai déjà essayé plein de sérums et huiles spécifiques pour mon alopécie. J’ai vu un changement avec le sérum Hact, plus de densité, des les premières semaines. Je ne saurais pas dire pour les repousses. En revanche, c’est un sacré budget. Mais je pense que les produits en valent la peine."

Marion P. (4/5)

"Le sérum Hact a pour premier avantage de ne pas graisser ni irriter le cuir chevelu. Fluide, discret, il s'applique facilement et ne laisse pas de dépôt. Mais le plus important est son efficacité! après quelques semaines, je constate déjà des bébés cheveux qui pointent, et un effet sur le volume et la densité. Je recommande!"

Fabienne A. (5/5)

Moi je suis qu'au début,

"Moi je suis qu'au début, Cela fait qu'un mois que j'utilise le serum et je peux vous dire que j'ai déjà vu un changement. Je perds beaucoup moins mes cheveux c'est impressionnant. Je perdait énormément mes cheveux et c'était pire sous la douche. J'ai refait une commande pour le serum. Hâte de voir dans 3 mois ou dans quelques mois pour vous faire un retour et avec les photos. Je vous remercie les filles car elles m'ont répondu à mes mails le jour même, elles sont à l'écoute si vous avez besoin. Je vous recommande le serum et j'en parle autour de moi. Merci les filles."

NATHANAELLE B. (5/5)

Utilisation très simple, ne graisse

"Utilisation très simple, ne graisse pas les cheveux! j'utilise depuis un mois, donc je ne peux pas vraiment parler de vraies repousses mais l'état générale de mes cheveux s'est nettement amélioré."

ANNARITA C. (5/5)

Sérum qui ne graisse absolument

"Sérum qui ne graisse absolument pas les cheveux, je fais la cure avec le derma stamp et le shampooing depuis 1 mois et demi alors je ne peux pas attesté de réels résultats pour le moment, peut être que mes cheveux s'épaississent un peu. Je vais dans tous les cas continuer cette routine."

Can the Anti-Hair Loss Serum No.1 be used during pregnancy or breastfeeding?

As a precaution, we recommend consulting a healthcare professional before using the Anti-Hair Loss Serum No.1. Its formula is 100% natural, hormone- and drug-free.

How long after application can I wash my hair?

The Anti-Hair Loss Serum No.1 does not make the hair greasy. We recommend leaving it on for several hours, ideally overnight, to allow the active ingredients to fully penetrate the scalp and work in depth.
Since it doesn’t leave any oily residue, there’s no need to wash your hair every morning, it’s entirely up to your preference.

Can the Anti-Hair Loss Serum No.1 cause hair growth on other parts of the body?

The Anti-Hair Loss Serum No.1 only stimulates hair growth on the scalp. It has no effect on hair on other parts of the body.
