This deep cleaning shampoo is a regular in my routine alongside with other scalp treatments, and it does wonders. I tried a lot of products from salon and farmacy and this performs really well. Previous to that i used Vichy dercos and it was good ( except that i hated the smell and the brassy feeling after washing my hair) but my scalp got user to it and i had to search for something else. I this that the fact that it contains zinc oxide makes it work. The scalp feels refreshed. The bad thing is that it kinda washes off the stain in my hair, but that with a long use only. (It is a treatment, not developed for daily use, so i am very happy with it and the fact that i don t have an itchy scalp anymore).
