The hair bulb sits in which skin layer?

Explanation:
The hair bulb is located in the dermis. Hair follicles extend from the surface of the skin into the dermal layer, and the bulb—the active-growth part at the base of the follicle—sits within the dermis near the dermal papilla that provides blood supply. The epidermis is the outer protective layer, with the stratum corneum being its outermost sublayer of dead cells, while the hypodermis lies below the dermis and contains fat. So the correct layer housing the hair bulb is the dermis.
