Alopecia areata is an autoimmune condition that causes hair loss in patches or across the scalp. It occurs when the immune system mistakenly attacks the hair follicles, leading to hair loss. The exact cause of alopecia areata is not fully understood, but it is believed to involve a combination of genetic and environmental factors. The condition can affect people of all ages and genders, and the extent and pattern of hair loss can vary from person to person. In some cases, alopecia areata may progress to total hair loss on the scalp (alopecia totalis) or loss of all body hair (alopecia universalis). There is currently no cure for alopecia areata, but treatment options are available to help manage the condition and promote hair regrowth. These may include topical corticosteroids, topical immunotherapy, oral medications, or injections of corticosteroids or other medications into the affected areas. It is important for individuals with alopecia areata to consult with a dermatologist to discuss treatment options, address any emotional or psychological impact, and receive ongoing care and support.
