I've always used the shampoo but decided to buy the pack whilst on sale and I do not regret it! it works amazingly on my dry weak hair, and i feel the difference after 2 weeks!
Des résultats remarquables en peu de temps
I use very little and it helps tame frizzy hair, smells great and provides pre-hot-iron protection for shiny hair. The small size makes it great for travel.
This is my second time ordering this product. Good stuff, and I will order it again!
My hair is so soft after this magic mask! Love it !

I bought this for my sister and she loves it. Her curls are enhanced, hair is soft and has more moisture and less frizz.
This product really works. My hair was fuzzy before using this and now I could blow dry and go. Adds moisture and shine.
Comme j’ai la peau sèche même en été, j’ai besoin d’un hydratant mais plus léger qu’en hiver et le gel collagène Native de GM Collin est parfait pour moi !
