Lasers in the management of alopecia: a review of established therapies and advances in treatment

AbstractAlopecia, also known as hair loss, is a highly prevalent condition affecting millions of men and women in the United States and worldwide, making it one of the most common complaints by patients presenting to a dermatologist. The symptomology on the presentation of alopecia can be highly variable, ranging from diffuse thinning of hair, discrete and localized patches completely absent of hair, or noticing significant shedding when brushing and showering. Although alopecia does not have a direct negative health impact on patients, it is nonetheless a debilitating disease as it can profoundly impact an individual ’s self-image and psychosocial well-being. There are multiple treatment options available to patients with alopecia, and they are typically tailored to the patient’s needs and preferences. The most common of these is the Food and Drug Administration-approved drugs for alopecia, minoxidil, and fi nasteride. However, both of these are known to be partially efficacious for all patients, so clinicians often use different modalities in conjunction with them, in particular laser-based therapies. This review article will provide a comprehensive assessment of lasers and other light therapies that m ay be used to manage the two most common types of alopecia: androgenetic alopecia and alopecia areata.
