Hair Dye Colors the Openings of Hair Follicles
Hair dye can sometimes alter the up close appearance of the scalp. Hair dyes can deposit on the scalp given the appearance of hyperpigmentation. In addition, the hair follicle openings or “pores” can take up pigment simulating the appearance of “dots.”
