Telogen Effluvium at the Back of the Head

Telogen effluvium happens when more hairs than usual shift into a resting phase and then shed. Because the change is often diffuse, the back of the head may look less dense when hair is parted, tied up, or viewed under bright light. Recent fever, illness, surgery, marked emotional strain, rapid weight change, or a medication change may be relevant. Hair loss seen at the back can also have other explanations, including friction, tight hairstyles, scalp inflammation, or patterned hair loss.

Look for clues such as shedding from many areas, short new hairs, broken hairs, scale, tenderness, or smooth sharply defined patches. These details help a clinician decide whether the pattern fits telogen effluvium or another scalp condition.

Take dated photographs of the crown, sides, and back using similar lighting, and write down when shedding began and what happened in the preceding weeks. Handle wet hair gently, avoid tight styles and repeated heat, and choose a balanced diet rather than starting several supplements without advice. A clinician may review medicines, examine the scalp, and request targeted tests when symptoms or history suggest a nutritional or hormonal contributor. Treatment options may include addressing the trigger and discussing [Topical Minoxidil](/treatments/hair-restoration/topical-minoxidil/) or other approaches when appropriate.

Arrange a medical assessment if shedding is persistent, rapidly worsening, or accompanied by scalp pain, burning, marked itch, redness, crusting, or smooth patches. Seek prompt care for sudden extensive loss, eyebrow or eyelash loss, or signs of infection such as warmth, pus, or fever. A dermatologist can assess the back of the head directly and explain whether the pattern resembles [Hair Loss](/symptoms/hair-loss/) from telogen effluvium or another cause.

Could the distribution at the back of my head reflect telogen effluvium, friction, or patterned loss? Which recent illness, stressor, medicine, or diet change matters most? Do I need scalp examination, blood tests, or a treatment trial? What changes should make me return sooner?
