I’m in love with this whole range I wish kerastase came out with it sooner it actually works my hair has improved so much I have noticed a big difference in the length and the thickness of my hair you literally only need a few drops all over your hair if you use too much like I’m guilty of sometimes it will leave your hair looking oily
