Hair Falling Out in Pregnancy: What to Know

Pregnancy hormones change the hair-growth cycle. Some people notice fuller hair, while others notice more shedding or a change in texture. Hair may also shed after delivery as the cycle adjusts again; this is different from sudden loss during pregnancy.

Diffuse shedding across the scalp can be associated with hormonal change, reduced iron stores, thyroid problems, fever, significant stress, or another recent illness. A sharply defined bald patch, broken hairs, scalp scale, redness, pain, or marked itching suggests a scalp or hair disorder such as alopecia areata or scalp ringworm. Tight hairstyles can contribute to traction alopecia, especially around the hairline.

Handle hair gently: use a wide-toothed comb, avoid vigorous brushing when wet, and choose looser hairstyles. Limit repeated heat, bleaching, relaxing, and tightly pulled braids or ponytails. Keep meals varied and mention persistent shedding to the clinician managing your pregnancy before starting supplements.

Do not start hair-loss medicines on your own during pregnancy. A clinician can review medicines, diet, recent illness, and family history, examine the scalp, and decide whether blood tests or a dermatology referral would help. Take a photo of the parting or affected area so changes can be compared over time.

Arrange a pregnancy-care or dermatology assessment if shedding is rapid, ongoing, or clearly patchy, or if you can see scalp through a widening part. Seek prompt advice for scalp pain, swelling, crusting, pus, pronounced scale, or intense itching. Also mention fatigue, feeling unusually cold or hot, dizziness, palpitations, or changes in weight, because these symptoms may point to a problem needing assessment during pregnancy.

Hair shedding alone is usually not an emergency, but sudden extensive loss or symptoms of feeling seriously unwell should be assessed without delay.

Ask: Does the pattern look like diffuse shedding, a patchy condition, or traction? Could iron or thyroid concerns be contributing? Which tests, supplements, shampoos, or treatments are appropriate during pregnancy? If shedding continues after delivery, when should it be reviewed?
