Hair Loss Due to Telogen Effluvium: What to Know

More hairs than usual enter the resting phase of the cycle at the same time. Shedding may become apparent weeks or months after fever, illness, surgery, rapid weight change, major stress, childbirth, or a medication change. Hair often comes out across the scalp rather than in a sharply defined patch. A widening part or thinner ponytail can be easier to notice than individual shed hairs. The trigger may have passed by the time shedding begins, so a careful timeline is useful. Telogen effluvium is different from a condition that progressively miniaturises follicles, although both can occur together.

Arrange an assessment if shedding is persistent, marked, or worrying. A clinician may examine the scalp and ask about recent illness, nutrition, menstrual or postpartum changes, stress, and medicines. Blood tests may be considered when symptoms suggest a thyroid problem, iron deficiency, or another contributor. Eat regular meals with adequate protein, avoid crash dieting, and handle wet hair gently. Reduce tight hairstyles, repeated bleaching, high heat, and vigorous brushing while the scalp is shedding. Do not start supplements or topical products without checking whether they fit your health needs; treatment should address an identified cause rather than the shed hair alone.

Seek prompt medical review for smooth bare patches, scalp pain, marked redness, heavy scale, pus, or broken hairs, because these findings can point to another scalp disorder. Arrange an appointment sooner if shedding is accompanied by fatigue, unexplained weight change, cold or heat intolerance, dizziness, or menstrual changes. A clinician can distinguish diffuse shedding from [Thinning Hair](/symptoms/hair-thinning/) and decide whether another diagnosis needs attention.

What event might have triggered my shedding, and does the timing fit? Should I have tests for thyroid function or iron status? Which hair-care changes are sensible for my scalp? Would [Hair Supplement Therapy](/treatments/hair-restoration/hair-supplement-therapy/) or [Topical Minoxidil](/treatments/hair-restoration/topical-minoxidil/) be appropriate for my diagnosis?
