As always, Garnier has fulfilled all my wishes with this mask. My hair looks like I just stepped out of the salon—incredibly smooth and shiny, and with natural ingredients, what more could I ask for? It’s the perfect step for frizz-free hair. I recommend you try it and see for yourself; you won’t be able to stop using it, just like I did.

I tried the product hoping it would really work since I have a lot of frizz. And after showering I was thrilled, plus it lasted for days and my hair still looks the same.

It is a high-performance straightener that works mechanically by sealing the cuticle and biologically by providing keratin, resulting in smooth, shiny and very manageable hair.
