Hair is derived from the epidermis, the outer layer of skin, but its roots extend deep into the dermis, the middle layer of skin.
The hair follicle is the structure that houses the hair. It originates in the epidermis but extends down into the dermis. The hair bulb, located at the base of the follicle, is where hair growth occurs.
Here's a breakdown of the skin layers and their relation to hair:
- Epidermis: This is the outermost layer of the skin and acts as a barrier. It's where the hair follicle begins.
- Dermis: This is the middle layer of the skin and contains blood vessels, nerves, and glands. It's where the hair follicle extends into, providing nourishment and support for hair growth.
Therefore, while hair originates in the epidermis, it extends deep into the dermis to anchor itself and grow.
