The trichology peel effectively removes any impurities & keratinized skin build-up which form the so-called crystallized layer. It unclogs the outlets of hair follicles & restores physiological balance to the scalp- which is the first essential step towards proper care for the scalp prone to hair loss & dandruff. Based on the complementary action of biological- enzymatic- & mechanical exfoliants (papain- apricot shells)- the peel deeply cleanses the scalp (removing dandruff- sebum- hair spray residues) & makes the hair less prone to oiliness. 125 ml
