The new OS Trichoset is made specifically for this pigmentation of the scalp. The pigments are color stable, because there are no iron oxides inside. Swiss technology and research ensure a product of excellent quality. (pigment size is less than 2 microns) The tricho pigments keep very well in the skin and they have a very good color stability.
