Folliculitis decalvans (FD) is a neutrophilic cicatricial alopecia characterized by erythematous follicular papules and pustules associated with follicular hyperkeratosis and tufted folliculitis. Here, we report the case of a 35-year-old man with recalcitrant FD successfully treated with Erbium-Yag (Er:YAG) laser, showing a rapid response and no hair loss. The effects on fibroblasts, skin microbiota, immune cascade, and angiogenesis are mechanisms through which the Er:YAG may improve FD, promoting hair growth and reducing hyperkeratosis. Nonetheless, further clinical studies are needed to investigate and better define its benefits.
