Ted Lain, MD, MBA, a board-certified dermatologist at Sanova Dermatology in Austin, Texas, shares his extensive experience with deuruxolitinib (Leqselvi) for the treatment of patients with moderate-to-severe alopecia areata. Drawing on 5 years of long-term extension data, Dr. Lain explains that patients generally maintained hair regrowth they achieved early in treatment, with no loss of effect over time. He emphasizes that this durability is crucial, as patients are often most afraid of losing newly regrown hair.
