Intralesional Steroid Injection

Intralesional steroid injection is one of the effective treatment methods frequently used, particularly in alopecia areata. In this method, a medication containing a corticosteroid is applied with very fine needles directly to the areas of hair loss.

The aim of treatment is to bring the inflammatory process under control by suppressing the immune response that damages the hair follicles, and to enable the hair to grow back. Applying the medication directly to the affected area makes the treatment effective in the targeted region. Intralesional steroid injection is one of the first treatment options, particularly in cases of alopecia areata affecting limited areas. It may be sufficient on its own in some patients, while in more widespread or resistant cases it can be combined with other treatment methods.

Treatment is applied at 3–4-week intervals. The number of sessions is planned according to the extent of the hair loss, the response to treatment and the development of new lesions, but is usually between 4 and 8 sessions in most patients. Hair growth usually begins within 4–8 weeks, although the response to treatment can vary from person to person. Any pain felt during the procedure is usually mild, and the application is completed within a few minutes. After the procedure, the patient can return to daily life immediately.

Besides alopecia areata, intralesional steroid injection can also be used in some cicatricial (scarring) alopecias to help bring the condition under control. In these patients, the treatment plan is determined according to the type, extent and activity of the condition.
