Correct answer: E — Telogen effluvium

Postpartum telogen effluvium is the most common cause of acute diffuse non-scarring hair loss in women of reproductive age. It occurs 2-4 months after the triggering event (delivery) when a large proportion of hair follicles synchronously enter telogen phase. Pull test is strongly positive with >10% club (telogen) hairs. Other triggers include high fever, surgery, severe illness, crash dieting, and emotional stress. The condition is self-limiting, resolving within 6-12 months. Reassurance is the mainstay of management. Anagen effluvium (from chemotherapy) shows hair breakage during the growth phase.
