Cosmetic hair care products are often implicated by the user or the clinician in cases of hair loss. Yet, these products are used ad lib, in a wide variety of home conditions and on a wide variety of hair types, by millions of consumers every day with no adverse effects. Based on this extensive data set, the absence of literature reports, and a detailed understanding of the mode of action of cosmetic hair care products, we can conclude that they do not cause hair loss. Clinicians investigating cases of hair loss must fully appreciate the hair cycle, the length of time a single fibre may be present on the head, and its biological and cosmetic history in order to understand the causes of hair loss and make the correct diagnosis. With a better understanding of the cosmetic practices used by everyday consumers, the clinician will be in a strong position to help patients re-grow their hair and guide them through a high quality hair care regime.
在脱发案例中，使用者或临床医生常常会将脱发归咎于美发护理产品。然而，这些产品每天被数百万消费者随意使用，使用环境多种多样，发质也各不相同，却并未产生不良影响。基于这一庞大的数据集、缺乏相关文献报道以及对美发护理产品作用方式的详细了解，我们可以得出结论：它们不会导致脱发。调查脱发病例的临床医生必须充分了解头发生长周期、单根头发在头上可能存在的时间长度及其生物学和美容史，以便理解脱发原因并做出正确诊断。更好地了解普通消费者的美容习惯后，临床医生将更有能力帮助患者重新生发，并指导他们采用高质量的头发护理方法。
