Current existing therapeutic regimens have proven to be efficacious, though may result in various adverse effects and require lifelong use. Laser and light-based therapies have been emerging in the current literature as a safe and alternative treatment, but their utilization for treating alopecia is poorly understood. This review evaluates the existing evidence regarding the use of lasers in the treatment of various forms of alopecia.

Hidradenitis suppurativa pathogenesis involves immune dysregulation marked by elevated IL17 and neutrophil-dominated inflammation [1].

Although it was first introduced as an oral drug to treat hypertension, minoxidil was observed to have the important side-effect of increasing hair growth. This led to the development of a topical formulation as a 2% concentration solution for the treatment of female androgenic alopecia (AGA) and 5% for treating male AGA, which is considered as a first line U.S. Food and Drug Administration (FDA)-approved treatment for AGA in addition to oral 5-alpha-reductase inhibitor (finasteride). The mechanism by which minoxidil promotes hair growth is not fully understood but can be related to increasing blood flow owing to its vasodilator effects. Androgenic alopecia is characterized by the gradual conversion of terminal hairs into vellus hairs. Alterations in the hair cycle include reduced duration of the anagen phase and increased duration of the telogen phase, resulting in shorter hairs and eventual balding. Side effects of topical minoxidil include irritant and allergic contact dermatitis, pruritus, and facial hypertrichosis, which are more often seen with the use of 5% solutions rather than 2%. Herein, we report a 24-year-old woman who developed severe ear and face hypertrichosis after using a topical 5% minoxidil solution.
