The new 3-clay mask shampoo gently purifies the scalp and hair. Many of us know the virtues of green clay to take care of the skin, but few imagine being able to use it on hair and yet ... its benefits are similar on our hair. This mixture of 3 clays elaborated exclusively at Biocoiff' allows to fight against dandruff, to absorb the excess of sebum, to regulate its secretion in depth and to purify the scalp. Our professional hairdressers use this shampoo before each coloring in order to purify the hair and eliminate all chemical residues.
