Unwanted pigmented hair is a common problem for many patients. Traditional methods of hair removal have included shaving, bleaching, plucking, waxing, use of chemical depilatories, and electrolysis. These techniques have been limited by their pain, inconvenience, and poor long-term efficacy. Only electrolysis has offered the potential for permanent hair removal. However, the technique is tedious, highly operator-dependent, and impractical for the treatment of large numbers of hairs. Recently, a number of lasers and other light sources have been developed specifically to target hair follicles. These include ruby, alexandrite, diode, and Nd:YAG lasers and an intense pulsed light source. These devices offer the potential for rapid treatment of large areas and long-lasting hair removal. This article explains the mechanisms of using light to remove hair, examines the attributes of specific laser systems, and explains the importance of patient selection and treatment protocol for the various systems in order to provide a safe and effective treatment.
unwanted色素沉着毛发对许多患者来说是一个常见问题。传统的脱毛方法包括剃须、漂白、拔毛、打蜡、使用化学脱毛剂和电解法。这些技术受到疼痛、不便和长期效果不佳的限制。只有电解法提供了永久性脱毛的可能性。然而，该技术繁琐，高度依赖操作人员，且不适用于大量毛发的治疗。最近，专门开发了一些激光和其他光源来靶向毛囊。这些包括红宝石激光、翠绿宝石激光、二极管激光和钕：钇铝石榴石激光以及强脉冲光源。这些设备提供了快速治疗大面积区域和持久脱毛的可能性。本文解释了利用光脱毛的机制，研究了特定激光系统的特性，并解释了患者选择和各种系统治疗方案的重要性，以便提供安全有效的治疗。
