Does the epidermis or the dermis produce skin and 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.
