Diet and hair falling out: what to know

Hair-producing cells need regular energy and nutrients. Skipping meals, rapid weight loss, a very limited diet, or poor appetite can reduce the supply available for new growth and may be followed by diffuse shedding. Low iron stores, inadequate protein, and some vitamin or mineral deficiencies can also contribute, but similar shedding may follow fever, major stress, surgery, pregnancy, or a medicine change. Patterned thinning, smooth bald patches, scalp scale, or broken hairs point toward other explanations such as Female Pattern Hair Loss, Male Pattern Hair Loss, Alopecia Areata, or Scalp Ringworm.

Return to regular meals and include a protein source such as eggs, fish, yoghurt, beans, lentils, tofu, or poultry. Add vegetables, fruit, whole grains, nuts, and seeds across the week. Iron-containing foods include meat, lentils, beans, and leafy greens; pairing plant sources with vitamin C foods can support iron absorption. Do not start high-dose supplements based on shedding alone: excess nutrients can also harm hair or health. Keep gentle hair care, avoid tight styles and harsh chemical processing, and track when shedding began. A clinician may review your diet, medicines, recent illness, scalp, and hair pattern and decide whether blood tests are appropriate.

Arrange an assessment if shedding is sudden, ongoing, patchy, associated with scalp pain or marked itch, or accompanied by fatigue, dizziness, menstrual changes, or unintentional weight loss. Seek prompt care for a rapidly spreading bald area, pus, severe scalp inflammation, or loss of eyebrows or eyelashes. Hair loss can be a symptom rather than a diagnosis; a clinician can distinguish nutritional shedding from Telogen Effluvium, Traction Alopecia, or another condition.

Could my recent diet, weight change, illness, or medicine be contributing? Do my scalp and hair pattern suggest a condition such as Telogen Effluvium or Alopecia Areata? Which tests, if any, would check iron or other deficiencies? Should I stop or change a supplement?
