Abstract
Photodynamic therapy (PDT) is used to stimulate and/or restore hair growth in areas of hair loss. Methods and compositions relating to PDT treatment for alopecia are disclosed. In light of PDT use to remove unwanted hair by inactivating or destroying hair follicles or destroying the tissue feeding the hair follicles, such methods and compositions relate to a surprising and unexpected discovery. PDT permits a means to treat conditions relating to hair loss such as androgenic alopecia, alopecia areata and drug-induced alopecia.
