"Many people see the finish effects of a dye and think that is it,"
says Mandy Baldwin, colour consultant and Trichologist. "But, the effect of the dye on your actual hair pigments, particularly for those lightening their hair isn’t evident to the naked eye. Ammonia strips the pigment from your hair so even with a hair colour remover the original virgin colour may not return as natural pigments have been stripped by the dye itself." There are four natural pigments in the hair. Black and Brown hair is created by melanin pigments and red and blonde hair is created by Pheomelanin pigments. These natural pigments are produced by cells known as melanocytes. The hairs natural colour depends on the ratio of pigment present, and the quantity and mixture.Mandy Baldwin
