Background: Alopecia areata (AA) is a chronic, organspecific autoimmune disease, probably 
mediated by autoreactive T cells, which affect hair follicles and sometimes the nails. The condition is 
often difficult to treat. Corticosteroids topically and intralesionally are useful but the injections can be 
painful in large patches. Objectives: This work aims to evaluate the role of microneedling in 
treatment of alopecia aerate. Methods: The study was conducted on 20 patients with alopecia aerata 
The age of patients ranged from 10 to 40 years. Results: Clinical improvement in most of cases which 
was in the form of increase in hair growth and density within affected areas. It started at about one 
month and complete about 3 months. Conclusion: microneedling is a good alternative for treating 
alopecia aerate.
