When hair loss appears suddenly in patches, dermatologists may recommend an alopecia areata skin biopsy to confirm the diagnosis. This test helps distinguish autoimmune hair loss from fungal infections, scarring alopecia, or nutritional causes.

During the procedure, the doctor numbs a small area of the scalp and removes a tiny skin sample. The process usually takes less than 15 minutes. Patients may feel mild pressure but no pain. Afterward, the site is covered with a small dressing and heals within a few days.

Biopsy results help dermatologists choose the most effective Alopecia Treatment Dubai plan, which may include injections, topical therapies, or immune-modulating medication.
