Chronic Telogen Effluvium: Is it a Distinct Condition? A Systematic Review

ConclusionsThe lack of a consensual consistent definition for chronic telogen effluvium is a significant limitation. Many cases presently labelled chronic telogen effluvium likely either represent early female pattern hair loss or incipient secondary telogen effluvium owing to an unidentified underlying secondary cause. Where triggering factors have been definitively excluded, hair shedding may represent an alteration in the hair cycle away from normal total asynchronous cycling. Some cases may also represent a preoccupation with normal hair shedding in anxious long-haired individuals.
