In which layer of the skin does the hair follicle originate?

• A. Epidermis
• B. Dermis
• C. Hypodermis
• D. Muscle layer

Answer: (B)

The hair follicle is a structure rooted in the dermis. During development it forms as an inward extension of epidermal cells, but the mature follicle—the bulb, root sheaths, and dermal papilla—resides within the dermal layer. The dermis provides the connective tissue support and blood supply that the follicle depends on, while the hair shaft itself grows upward and passes through the epidermis to reach the skin surface. So, while its origin involves epidermal cells, the overall location of the hair follicle is in the dermis.
