One of the hormones that affects the pilosebaceous unit is androgen, a steroid hormone that plays an important role in the expression of the phenotype of men and women. Androgen consist of testosterone and dihydrotestosterone which are activated by androgen receptors. Androgen in the pilosebaceous unit affect sebum production and hair growth. Androgen receptors in the sebaceous glands are found on sebocytes and in hair follicles in the dermal papillae of hair follicles
