Before and after telogen effluvium

Before recovery, extra hairs may collect in the shower, brush or on clothing, while the scalp generally looks normal. During improvement, shedding slows and short new hairs become noticeable, although density takes longer to look restored.

A physical or emotional stressor can shift many growing hairs into a resting phase at around the same time. Those hairs are later released from the follicles, so shedding may begin after the triggering illness, major stress, nutritional problem, medication change or hormonal event rather than immediately.

Telogen effluvium commonly presents with diffuse hair loss or thinning across the scalp instead of a sharply defined bald patch. New growth and continued shedding can overlap, which means early regrowth does not always make the hair look fuller straight away.

Handle the hair gently: avoid tight styles, vigorous brushing, repeated high heat and harsh chemical processing while shedding is active. Eat a varied diet with adequate protein, and discuss supplements before taking them because unnecessary high-dose products can be harmful or obscure the real cause.

Photographs taken under similar lighting and with the same part can show trends more reliably than counting shed hairs. A clinician may review recent health events, medicines, diet, menstrual or thyroid symptoms and examine the scalp before deciding whether blood tests or treatment are useful.

Seek medical advice if shedding is persistent, rapidly worsening, occurring in patches, or accompanied by scalp pain, redness, scaling, scarring or broken hairs. Assessment is also appropriate when hair loss comes with marked fatigue, unexplained weight change, heavy menstrual bleeding or other symptoms that could identify a treatable trigger.

Get prompt care for sudden hair loss after starting a medicine if you also develop facial swelling, breathing difficulty or a widespread blistering rash. Do not stop a prescribed medicine without advice unless emergency clinicians direct you to do so.

Ask whether the pattern fits telogen effluvium, which recent events or health conditions could be triggers, whether scalp examination or blood testing is warranted, and how you will judge recovery. If considering topical minoxidil, PRP or supplements, ask what problem each option is intended to address and what side effects or limitations apply.
