Final answer:
The dermis layer of the skin contains hair follicles.
Step-by-step explanation:
The layer of the skin that contains hair follicles is the dermis.
The dermis is the layer of skin directly under the epidermis, and it is made of tough connective tissue. It contains hair follicles, sweat glands, oil glands, and blood vessels.
For example, when you pluck a hair from your skin, you are pulling it out from the dermis.
