Question: 1 / 400

Where are hair follicles located in the skin?

Epidermis

Dermis

Hair follicles are located in the dermis, which is the second layer of the skin situated beneath the epidermis. The dermis contains vital structures such as blood vessels, nerve endings, and hair follicles. This layer provides the necessary environment for hair growth and development, as it houses the hair root and associated structures like sebaceous glands.

The epidermis, which is the outermost layer of the skin, does not contain hair follicles; instead, it serves as a protective barrier. The stratum corneum is the outermost part of the epidermis and consists mainly of dead skin cells that help in the barrier function of the skin. The hypodermis, or subcutaneous tissue, lies beneath the dermis and primarily functions to anchor skin to underlying structures and provide insulation and cushioning. Thus, the correct answer highlights the dermis as the essential layer where hair follicles are found.
