Telogen effluvium (TE) is one of the most common causes of diffuse nonscarring hair loss. In its acute form, it generates a lot of anxiety in the patient, which can be significantly allayed with a confident diagnosis. In its more chronic form, however, the hair loss may go unnoticed for long periods of time. Here in, the dermatologist's role in differentiating it from the more common patterned hair loss is significant. Differentiating TE from other causes of diffuse nonscarring hair loss can indeed be a daunting task and TE is often used as a waste basket diagnosis. A number of factors have been implicated in the causation of TE, however, clear evidence in their support is lacking. The role of stress as a causative factor as well as the result of hair loss needs to be adequately understood. This review aims at summarizing our current level of knowledge with respect to this very common cause of hair loss. An attempt is made to help the readers reliably differentiate TE from other causes of diffuse nonscarring hair loss. The possible causative factors, pathogenetic mechanisms, clinical presentation, and possible treatment options are discussed.
休止期脱发（TE）是弥漫性非瘢痕性脱发最常见的原因之一。在急性形式中，它会给患者带来很大的焦虑，而自信的诊断可以显著缓解这种焦虑。然而，在更慢性形式中，脱发可能会在很长一段时间内未被注意到。在这里，皮肤科医生在将其与更常见的模式性脱发区分开来的作用非常重要。将 TE 与其他弥漫性非瘢痕性脱发的原因区分开来确实是一项艰巨的任务，而 TE 通常被用作一个笼统的诊断。有许多因素与 TE 的发病有关，但缺乏明确的支持证据。压力作为致病因素以及脱发的结果需要得到充分理解。这篇综述旨在总结我们目前对这种非常常见的脱发原因的了解程度。试图帮助读者可靠地区分 TE 与其他弥漫性非瘢痕性脱发的原因。讨论了可能的致病因素、发病机制、临床表现和可能的治疗选择。
