Alopecia Areata is a recurrent and non scarring type of hair loss in single or multiple patches that can affect any hair-bearing area. Alopecia Areata can present with many different patterns from person to person. Alopecia Areata is a benign condition and most patients are asymptomatic; however, it can cause emotional and psychosocial stress in affected individuals. Self-consciousness concerning personal appearance can become important. These issues are to be discussed openly with the doctor which can help significantly in coping with the problem. Positive family history is the only known responsible factor as a cause. The exact role of stressful events is not clear but they are likely to trigger a condition which is already present in susceptible individuals. The natural history of Alopecia Areata is unpredictable. Most patients have only a few focal areas of alopecia, and spontaneous regrowth usually occurs within 1 year. Probably, less than 15% of patients experience extensive alopecia, and less than 3% have Alopecia Universalis. Patients with extensive long-standing conditions are less likely to experience significant long-lasting regrowth. Adverse prognosis factors include nail deformities, allergic conditions, onset at a young age, and severe forms of Alopecia Areata. No treatment is effective in preventing or halting progression of the condition. No trigger can be found to explain disease exacerbation in most patients.
