Effective alopecia treatments include applying anthralin ointment or cream, using a 5 percent solution of minoxidil, or cortisone injections, states the National Alopecia Areata Association. Hair may grow again even in untreated bald areas. When they stimulate hair follicles properly, alopecia patients can regrow hair years after hair loss.
Although no single type of treatment is successful in every case, dermatologists use cortisone injection treatments most frequently, notes the National Alopecia Areata Association. Dermatologists use miniature needles to administer the injections monthly once patients begin their treatments. Anthralin is a man-made product with a consistency similar to tar that patients apply daily for about two to three months. Patients with less than total hair loss may see results when they apply topical minoxidil solution two times each day.
