A hair follicle is part of the skin that grows hair by packing old cells together. Attached to the follicle is a sebaceous gland, a tiny sebum-producing gland found everywhere except on the palms, lips and soles of the feet. The thicker density of hair, the more sebaceous glands are found.
Also attached to the follicle is a tiny bundle of muscle fiber called the arrector pili that is responsible for causing the follicle lissis to become more perpendicular to the surface of the skin, and causing the follicle to protrude slightly above the surrounding skin (piloerection). This process results in goose bumps (or goose flesh). Stem cells are located at the junction of the arrector and the follicle, and are principally responsible for the ongoing hair production during a process known as the Anagen stage.
The average growth rate of healthy hair follicles on the scalp is 400 µm per day.
Certain species of Demodex mites live in the hair follicles of mammals (including those of humans) where they feed on sebum.

What else can I help you with?
What is hair composed of?
Hair is composed of a protein called keratin, which is produced by hair follicles in the skin.
Is hair primarily composed of dead skin cells?
Yes, hair is primarily composed of a protein called keratin, which is produced by hair follicles in the skin. While hair itself is not alive, it is formed from living cells in the hair follicles.
Sheath formed of both epithelial and connective tissues?
This structure is likely a dermal sheath, which is composed of both the epidermis (epithelial tissue) and the dermis (connective tissue). Dermal sheaths surround some hair follicles and play a role in supporting and nourishing the hair follicle.
In which layer of the skin are hair follicles embedded?
Hair follicles are embedded in the dermis layer of the skin.
How many genes does hair have?
Human hair does not contain genes. Hair is composed of a protein called keratin, which is produced by hair follicles located in the skin. The traits of your hair, such as color, texture, and thickness, are determined by your genetics.

What are the follicles composed of?
Follicles are composed of hair, sebaceous glands, and arrector pili muscles. The hair follicle is a tunnel-like segment of the epidermis that extends down into the dermis of the skin.
