What autoimmune disorder is characterized by hair falling out in round patches?

Alopecia areata is an autoimmune disorder that leads to hair falling out in round patches. This condition occurs when the immune system mistakenly targets hair follicles, resulting in sudden, localized hair loss. The size and number of patches can vary, and they can appear on the scalp or other areas of the body.

Understanding alopecia areata is crucial for barbers and stylists, as they may encounter clients experiencing this condition. Recognizing the symptoms not only helps in providing sensitive and informed service but also allows for better client communication regarding hair care and styling options that may accommodate their unique situation.

On the other hand, psoriasis is primarily a chronic skin condition that results in red, scaly patches, and does not primarily manifest as hair loss. Dermatitis refers to inflammation of the skin and can cause irritation but is not typically associated with the sudden patchy loss of hair. Telogen effluvium is characterized by temporary hair shedding due to stress or hormonal changes, rather than well-defined patches of hair loss.
