Our solid shampoo is completely sulfate free. It uses mild surfactants. This is why there is no aggressive effect on the scalp. And after 3-5 use, the scalp begins to produce much less sebum. And you will need to wash your hair less often!
The shampoo foams a lot, cleans the scalp "to a squeak", but without overdrying it.
It is worth trying at least once.
From the first use you will feel its effect, in time you will not return to the usual shampoo stores
