What causes postpartum hair loss?

During pregnancy, hormonal changes can keep more scalp hairs in their growing phase. After delivery, those hairs may move into a resting phase and then fall out around the same period. Shedding may be most noticeable while washing, brushing, or seeing hair on clothing. This process is called telogen effluvium and usually affects the scalp diffusely rather than creating one sharply defined bald patch. A difficult delivery, low iron, thyroid changes, illness, rapid weight change, or restricted eating can add to shedding, so the timing alone does not prove one cause.

New short hairs along the hairline can appear as the cycle resets. Hair density may take time to look fuller because each strand grows gradually.

Use a gentle shampoo, detangle with care, and avoid tight ponytails, extensions, frequent bleaching, and high heat while the scalp is shedding. Eat regular meals with adequate protein and discuss iron or thyroid testing if shedding is heavy, prolonged, or accompanied by fatigue, cold sensitivity, or changes in weight. Do not start high-dose supplements without checking whether you need them. A dermatologist can distinguish postpartum shedding from another form of hair loss and discuss options such as Hair Supplement Therapy or Topical Minoxidil when appropriate.

Arrange a clinical assessment if hair loss is patchy, the scalp is painful, very itchy, inflamed, or scaly, or the shedding continues without improvement. Seek prompt medical advice for sudden extensive loss, eyebrow or eyelash loss, or signs of infection. These patterns can point to a condition other than routine postpartum shedding and may need examination and targeted tests.

Ask whether the distribution fits postpartum shedding, whether iron or thyroid checks are sensible, and which styling changes could reduce breakage. You can also ask when treatment is appropriate and how to use it safely if you are breastfeeding or planning another pregnancy.
