As early as the 19th century, physicians have attempted to achieve permanent hair removal with employment of electrolysis, initially for the treatment of trichiasis.1 With the development of laser technology, the field of hair epilation has vastly expanded in recent years. Laser hair removal (LHR) has revolutionized the field of hair removal in large part due to the ability to selectively target and destroy hair follicles, leading to more long-lasting hair removal, requiring less operator dependency, and decreasing the potential side effects compared with other methods of hair removal. However, despite these advantages, it is of paramount importance for safe, effective LHR that the laser/light device operator has a basic understanding of laser–skin interactions including proper patient/laser selection as well as an understanding of hair anatomy, growth, and physiology.
