GENERAL HISTOLOGY

Detailed explanation-1: -The visible hair shaft is the only part that is not anchored to the hair follicle and the shape plays a role in determining hair texture. The rest of the hair (hair root) is anchored in the follicle and lies below the surface of the skin (Fig 1).

Detailed explanation-2: -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.

Detailed explanation-3: -The hair follicle begins at the surface of the epidermis. For follicles that produce terminal hairs, the hair follicle extends into the deep dermis, and sometimes even subcutis. Meanwhile, follicles producing vellus hairs extend only to the upper reticular dermis.
