What should you know about chronic telogen effluvium?

Telogen effluvium happens when more hairs than usual move into the resting and shedding phase. With a chronic pattern, hair may come out during washing, brushing or styling over an extended period. People often notice a thinner ponytail or more scalp visibility, while the hairline may remain broadly intact.

Possible contributors include illness, major stress, dietary restriction, hormonal change, low iron or thyroid problems. The shedding itself does not establish which trigger is responsible. A clinician may review your timeline, examine the scalp and consider blood tests; other types of hair loss can coexist and need different care.

Write down when shedding began, recent illnesses, weight or diet changes, new medicines and menstrual or hormonal changes where relevant. Eat regular balanced meals with adequate protein, avoid tight styles and reduce repeated heat or chemical processing. Treating a confirmed contributor is usually more useful than starting several products at once.

A dermatologist may discuss topical minoxidil, supplement therapy when a deficiency is found, or procedures such as platelet-rich plasma in selected cases. Ask what evidence and monitoring apply to your situation before choosing a treatment.

Seek assessment if shedding continues, accelerates, or is accompanied by scalp pain, scale, redness, itching, broken hairs, smooth patches, eyebrow loss or marked fatigue. Prompt review is also sensible after a new medicine or a significant dietary change. Sudden patchy loss or an inflamed scalp may point to a different condition.

Ask whether the pattern is consistent with telogen effluvium, which triggers should be checked, and whether your scalp shows another form of hair loss. Ask when improvement should be expected after a trigger is corrected, whether testing is appropriate, and how progress will be measured.
