PATHOLOGY

Detailed explanation-1: -Hair has only two types of pigments: dark (eumelanin) and light (phaeomelanin). They blend together to make up the wide range of hair colors. Melanin is made up of specialized pigment cells called melanocytes. They position themselves at the openings on the skin’s surface through which hair grows (follicles).

Detailed explanation-2: -At the base of the hair follicle/hair bulb, there is a dermal papilla, which contains the blood supply for the hair. The hair matrix, which contains the proliferating cells that generate the hair and the internal root sheath, is just above the dermal papilla, and separated from it by a basement membrane.
