The matrix which produces it and the hair papilla contains blood vessels that nourish the hair follicles.
Hair follicles.

Hair follicles are accessory organs to the integumentary system. They are located in the dermis and are responsible for producing hair.
The epidermis is primarily responsible for producing skin, specifically the outermost layer that acts as a barrier. Hair, however, is produced in the dermis, where hair follicles reside. The dermis contains the necessary structures and cells, such as hair follicle stem cells, that facilitate hair growth. Thus, while both layers contribute to skin and hair, the epidermis produces the skin surface, and the dermis is essential for hair production.
Sebaceous glands, errector pili, and hair are all accessory organs or appendages of the skin that are rooted in the dermis. The epidermis is a layer of the skin, and is on top of and separate from the dermis.
The hair follicle is located in the dermis and extends into the hypodermis. The hair bulb, which contains the hair papilla and matrix cells responsible for hair growth, is situated at the base of the hair follicle in the dermis.
villi
Fully developed hair follicles lie in the dermis but develop as indurations from the epidermis.
in the dermis there is the hair shaft, oil and sweat glands, follicle, and muscle.
Hair grows from hair follicles, which are small cavities in the skin that produce hair.
in the dermis there is the hair shaft, the follicle, the oil and sweat glands, and the nerve fiber.
The growth of epidermal cells into the dermis forming a small tube is known as a hair follicle. During development, epidermal cells invaginate into the dermal layer, creating a structure that houses the hair shaft and associated glands. This interaction between epidermal and dermal cells is crucial for hair growth and the overall health of the skin. The follicle plays a significant role in the hair growth cycle and in the regeneration of hair.
