GENERAL HISTOLOGY

Detailed explanation-1: -Hair follicles are structures within your skin that grow your hair. You’re born with millions of hair follicles in your skin. You can’t pull out hair follicles.

Detailed explanation-2: -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.

Detailed explanation-3: -The hair follicle root, which is located 4mm under the epidermis, includes sebaceous glands and interacts with the associated structures (epidermis, dermis, arrector pili muscles, vascular system).
