complete scalp hair loss due to autoimmune disorder
Alopecia Totalis (AT) is an advanced form of alopecia areata characterized by the complete loss of hair on the scalp. Unlike alopecia areata, which typically presents as patchy hair loss, AT results in total baldness of the head. This condition is believed to be an autoimmune disorder, where the body's immune system mistakenly attacks hair follicles, leading to hair loss.
