Very nice shampoo for use after keratin treatment. It cleans them very well and they are smooth and soft. And of course, its price is worth it.

I had a keratin treatment a year and something ago, after that I was using a very good shampoo and mask, professionally and expensive, my hair was never very soft but it straightened quite easily and because I have a lot, frizzy and voluminous hair it somehow reduced the volume (which I wanted), now before doing the treatment again I decided to try to see if a shampoo without salt alone would do some work in the volume part, I bought this shampoo and its mask together .... I was amazed ... they are softer than before, they straighten a bit less compared to the treatment, the volume is what I wanted, I think I'm done with the 150€ treatment!
