Ultraviolet Light Treatment for Alopecia Areata
UV Light Treatment, also known as ‘Light Therapy’ or ‘Phototherapy’, is sometimes considered a treatment for hair loss from alopecia, however it is not usually recommended.
This type of hospital-based therapy is not a popular choice because of the poor results it tends to produce, its high relapse rate, and side effects which range from nausea and changes in skin pigmentation to an increased risk of skin cancer.
Those who do undergo UV Light Treatment have two to three sessions per week where the skin is exposed to ultraviolet light (UVA or UVB rays). Sometimes patients will also be given psoralen, a medicine that makes the skin more sensitive to light, before treatment.
