A variety of laser technologies are now able to successfully remove unwanted hair. Successful removal is based on an understanding of laser physics and appropriate wavelengths, pulse durations and cooling of the skin. Although ruby lasers were among the first to be used, alexandrite, diode and neodymium-doped yttrium aluminium garnet (Nd:YAG) lasers, as well as a variety of broad-spectrum intense pulsed light sources, are currently more commonly used for the treatment of unwanted hair. Darker skin types are more difficult to treat but can also be treated. Complications can occur after laser hair removal but can be reduced through an understanding of the fundamentals of laser removal. These complications include the obvious, such as scarring and pigmentary changes, and the not so obvious, such as reticulate erythema and uveitis. Laser hair removal is now widely accepted as a successful approach to remove unwanted hair in both men and women. The future will involve office-based laser and light source hair removal, as well as a variety of laser and light-based home devices.
如今，多种激光技术已能够成功去除多余毛发。成功去除毛发基于对激光物理学以及合适波长、脉冲持续时间和皮肤冷却的理解。尽管红宝石激光是最早被使用的激光之一，但翠绿宝石激光、二极管激光、掺钕钇铝石榴石（Nd:YAG）激光以及多种广谱强脉冲光源，目前更常用于治疗多余毛发。肤色较深的人群更难治疗，但也可以进行治疗。激光脱毛后可能会出现并发症，但通过了解激光脱毛的基本原理可以减少这些并发症。这些并发症包括明显的，如瘢痕形成和色素沉着变化，以及不太明显的，如网状红斑和葡萄膜炎。激光脱毛如今已被广泛认可为一种成功的去除男女多余毛发的方法。未来将包括基于诊所的激光和光源脱毛，以及各种基于激光和光的家用设备。
