A hair follicle is a tube-like structure (pore) that surrounds the root and strand of a hair. Hair follicles exist in the top two layers of your skin. You're born with over 5 million hair follicles in your body and over one million hair follicles on your head. As you age, hair grows out of your hair follicles.

The hair bulb is the lowest expanded extremity of the hair follicle that fits like a cap over the dermal hair papilla, enclosing it.The dermal hair papilla is a cluster of mesenchymal cells giving rise to several capillaries, which form a capillary loop. The hair bulb generates the hair and its inner root sheath. The bulb consists of two parts: germinal matrix and the upper bulb.

Excerpt. The structural, or pilosebaceous, unit of a hair follicle consists of the hair follicle itself with an attached sebaceous gland and arrector pili muscle. 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.
