Roll on très pratique et très efficace j'ai pleins de petits cheveux qui ont repousser. J'avais un trou devant et mes cheveux ont repoussé

### 4.0/5 · Coline D. · April 16, 2023
J'ai commencé à l'utiliser il y a quelques semaines seulement, donc difficile de donner un avis, mais j'ai le sentiment que c'est un très bon produit. Seul bémol, c'est la taille du Roll-on, il est vraiment petit et comme je l'utilise toutes les semaines il ne va pas faire long feu...

Incroyablement efficace pour aider les trous causés par des queues de cheval hautes trop serrées!! C'est devenu un de mes produits préférés

### 3.0/5 · Lea M. · February 11, 2023
La compo est top et les effets sont la également. 
La note n’est pas la meilleure simplement pour le rapport quantité prix. Le tube est tout petit.

A tester, pas assez de recul. Flacon assez petit.
