Telogen effluvium is the excessive loss of normal club hairs. It can be diagnosed simply by microscopic examination of the hairs that are being shed. These hairs have uniform shaft diameter and normally shaped bulbs that contain no pigment. ⋯ It is usually not accompanied by inflammatory changes and the prognosis is excellent provided the causative styling practices-braids, rollers, ponytails, etc-are discontinued. Telogen conversion may be caused by interference with papillary blood flow. Since traction alopecia would seem to be reproducible, it may serve as a model for the study of telogen conversion.
