The perception of unwanted hair is culturally dependent, and its removal is a multibillion-dollar business in North America each year. Examples of hair removal techniques on the market today include shaving, depilatories, wax, epilation, electrolysis and photo-epilation. Electrolysis, or electrothermolysis, was the only known permanent hair removal modality to date. However, long term or permanent hair removal with lasers is becoming a reality for treatment of hirsuitism or unwanted hair. Laser hair removal is an exciting new field with improvements occurring continually, making it difficult to stay abreast of the newest treatments and their effectiveness. This review provides an overview of hair follicle anatomy, mechanisms of photo-destruction to hair follicles and physics of lasers and the skin. The different types of lasers used for hair removal, their mechanisms and clinical research are reviewed.
对多余毛发的认知因文化而异，每年在北美，去除毛发是一项价值数十亿美元的业务。当今市场上的脱毛技术包括剃须、脱毛膏、蜡疗、脱毛器、电解脱毛和光脱毛。电解脱毛，即电热脱毛，是迄今为止唯一已知的永久性脱毛方式。然而，使用激光进行长期或永久性脱毛正成为治疗多毛症或多余毛发的现实方法。激光脱毛是一个令人兴奋的新领域，不断有改进，很难跟上最新治疗方法及其效果。本综述概述了毛囊解剖结构、毛囊光破坏机制、激光和皮肤的物理学原理。还综述了用于脱毛的不同类型激光、其作用机制和临床研究。
