What should you know about diet and hair loss?

Growing hair depends on a steady supply of energy and nutrients. Restrictive eating, skipped meals, poor appetite, digestive problems, or rapid weight loss can place the body under strain. Hair may shift from active growth into a resting phase, with increased shedding noticed later.

A dietary link does not rule out other explanations. Male or female pattern changes, alopecia areata, scalp ringworm, traction from tight styles, and telogen effluvium can all affect hair. The pattern on the scalp and the timing of symptoms help distinguish them.

Choose a varied eating pattern with enough total food and a regular protein source. Include iron-containing foods and a range of vegetables, fruit, grains, nuts, or seeds as suitable for your preferences and health needs. If you follow a restrictive diet, ask a clinician or dietitian how to meet nutrient needs safely.

Record the start of shedding, changes in appetite or weight, recent fever or illness, stress, new medicines, and styling practices. A clinician may examine the scalp and decide whether blood tests or other checks are appropriate. Treating a deficiency can help when one is present, but supplements do not replace diagnosis.

Book an assessment for persistent shedding, widening parting, a receding hairline, smooth patches, broken hairs, or an itchy and scaly scalp. Seek prompt advice if hair changes accompany severe tiredness, dizziness, unexpected weight change, or signs of infection. Do not assume diet is responsible from shedding alone.

Does my scalp pattern fit a nutritional problem or another diagnosis? Could my medicines, illness, or recent weight change affect the hair cycle? Would testing be useful, and how can I change my diet without taking unnecessary supplements?
