Qu’est-ce que Panthrix ?
Panthrix est une lotion capillaire autrichienne. Elle s’applique sur le cuir chevelu et ne se rince pas. Son actif principal est le Redensyl, une matière première cosmétique qui, selon son fabricant, agit sur les cellules souches de la racine du cheveu. Panthrix ne contient ni minoxidil ni hormones.
Redensyl : ce que montrent les études
L’étude principale est une étude pilote du fabricant de la matière première, menée sur 26 hommes : 14 ont appliqué une lotion à 3 % de Redensyl, 12 une lotion sans actif, pendant 84 jours. Selon le fabricant, il y avait ensuite davantage de cheveux en phase de croissance et moins en phase de chute. Aucune femme n’a été étudiée, et aucune reproduction indépendante n’existe. Des slogans comme « des dizaines de milliers de nouveaux cheveux » ou « mieux qu’une greffe de cheveux » nous paraissent donc exagérés.
Pour en savoir plus sur l’actif lui-même, lisez notre article sur le Redensyl.
Le plus : sans minoxidil ni hormones, sans ordonnance.
Le plus : l’actif reste sur le cuir chevelu, il n’est pas rincé.
À savoir : deux fois par jour – le matin, cela se sent aussi aux racines.
À savoir : études uniquement sur la matière première, de petite taille et menées par le fabricant.

Nous sommes coiffeurs, pas médecins. Données selon le distributeur, les revendeurs et le fabricant de la matière première, octobre 2026. En cas de chute de cheveux soudaine ou importante, faites-en rechercher la cause par un médecin.
