Our intent was to determine the effectiveness of the 308 rim excimer laser for the treatment of scalp psoriasis through a non‐blinded, randomized, controlled study. Institutional approval for this study was achieved. Twenty consecutive volunteers with stable large plaques of scalp psoriasis were enrolled. Mineral oil was applied before each treatment. A modified psoriasis area severity index (PASI) score was determined before each treatment. Excimer laser generated 308‐rim (Photomedex, San Diego, CA, Model #AL 7000) UV‐13 radiation was administered evenly to each large plaque of scalp psoriasis twice weekly for up to 30 treatments. Untreated areas of adjacent scalp psoriasis served as controls. Each plaque received a set dose of radiation based on a predetermined minimal erythema dose. The dose of radiation was increased incrementally at each visit, as tolerated. There was a clear improvement as assessed by the mean PASI scores for treated vs. untreated plaques of scalp psoriasis. Adverse effects were minimal. The 308 nm excimer laser is a safe, novel and effective method of treating scalp psoriasis.
