Detailed explanation-1: -A hair follicle anchors each hair into the skin. The hair bulb forms the base of the hair follicle. In the hair bulb, living cells divide and grow to build the hair shaft. Blood vessels nourish the cells in the hair bulb, and deliver hormones that modify hair growth and structure at different times of life.
Detailed explanation-2: -The dermal papilla contains capillaries. The papilla interacts with the matrix, which has the highest mitotic rate of any organ. The matrix is the part of the hair follicle where matrix keratinocytes proliferate to form the hair shaft of growing hair.
Detailed explanation-3: -The hair follicle is a tube-shaped sheath that surrounds the part of the hair that is under the skin and nourishes the hair. It is located in the epidermis and the dermis.
