there are two major isoforms of 5α-reductase, srd5a1 (type i) and srd5a2 (type ii), with the latter being the most biologically important isoenzyme. there is also third 5α-reductase: srd5a3. srd5a2 is most highly expressed in the genitals, prostate gland, epididymides, seminal vesicles, genital skin, facial and chest hair follicles, and liver, while lower expression is observed in certain brain areas, non-genital skin/hair follicles, testes, and kidneys. srd5a1 is most highly expressed in non-genital skin/hair follicles, the liver, and certain brain areas, while lower levels are present in the prostate, epididymides, seminal vesicles, genital skin, testes, adrenal glands, and kidneys. in the skin, 5α-reductase is expressed in sebaceous glands, sweat glands, epidermal cells, and hair follicles. both isoenzymes are expressed in scalp hair follicles, although srd5a2 predominates in these cells. the srd5a2 subtype is the almost exclusive isoform expressed in the prostate gland.

the formation of granulation tissue into an open wound allows the reepithelialization phase to take place, as epithelial cells migrate across the new tissue to form a barrier between the wound and the environment. basal keratinocytes from the wound edges and dermal appendages such as hair follicles, sweat glands and sebacious (oil) glands are the main cells responsible for the epithelialization phase of wound healing. they advance in a sheet across the wound site and proliferate at its edges, ceasing movement when they meet in the middle. in healing that results in a scar, sweat glands, hair follicles and nerves do not form. with the lack of hair follicles, nerves and sweat glands, the wound, and the resulting healing scar, provide a challenge to the body with regards to temperature control.
