Persistent diffuse shedding lasting more than six months, often with no single obvious trigger.
Chronic telogen effluvium is a prolonged form of increased shedding. It is most often discussed in women and can be frightening because the amount of hair lost each day may look dramatic. The scalp usually does not show scarring, and complete baldness is not expected. Diagnosis is partly clinical and partly by excluding other causes such as female pattern hair loss, thyroid disease, iron deficiency, medication-related shedding and diffuse alopecia areata. Treatment focuses on identifying triggers, correcting reversible factors and reassuring patients about the usually non-scarring nature of the condition.
