Steroids alopecia areata

Steroid injections can prevent the immune system from attacking hair follicles in alopecia sufferers . This, in turn, can lead to hair regrowth. The treatment involves a steroid solution being injected directly into the scalp a number of times, and this may need to be repeated every few months. Whilst this treatment option is best suited to those with smaller patches of hair loss, it is still worth considering the long-term side effects of steroid injections which, ironically, can include premature balding. Steroid injections can also be extremely uncomfortable and painful.

A key aspect of hair loss with age is the aging of the hair follicle. [40] Ordinarily, hair follicle renewal is maintained by the stem cells associated with each follicle. Aging of the hair follicle appears to be primed by a sustained cellular response to the DNA damage that accumulates in renewing stem cells during aging. [41] This damage response involves the proteolysis of type XVII collagen by neutrophil elastase in response to the DNA damage in the hair follicle stem cells. Proteolysis of collagen leads to elimination of the damaged cells and then to terminal hair follicle miniaturization.
