Why hair may fall out three months postpartum

Loose hair can seem most obvious during washing or brushing, and the temples may look less full. A widespread change with a normal-looking scalp is more consistent with cycle-related shedding than a smooth isolated bald spot.

Pregnancy hormones can delay the release of resting hair. When hormone levels change after birth, a larger group of follicles can move through rest and shedding together. Dermatologists call this type of diffuse shedding telogen effluvium.

Shedding does not reveal the cause by itself. Iron deficiency, thyroid disturbance, a recent fever, restricted eating, scalp disease, or female pattern hair loss may overlap with the postpartum change. The distribution and accompanying symptoms help distinguish them.

Choose loose hairstyles, detangle from the ends, and limit straighteners, bleaching, and pulling extensions. These measures cannot stop hairs that have already entered the shedding phase, but they reduce avoidable breakage and traction.

Eat regularly and include protein, iron-containing foods, fruit, vegetables, and sufficient fluids. Do not assume that a hair supplement is necessary: excess amounts of some nutrients can be unhelpful, and the right choice depends on your health and diet.

Arrange an assessment for bald patches, widening that follows a clear pattern, marked scalp itch, scale, sores, tenderness, or broken stubble. Also report palpitations, persistent exhaustion, feeling unusually cold, heavy bleeding, or other new health symptoms.

See a clinician if the hair fall remains severe, continues to worsen, or shows no sign of settling. Examination may identify regrowth, inflammation, traction, or patterned thinning, and the history can guide whether laboratory testing is warranted.

Bring a list of medicines and supplements, describe recent illness and bleeding, and note whether relatives have patterned thinning. Ask what pattern the examination shows, whether testing for iron or thyroid problems fits your symptoms, and which options are compatible with breastfeeding.
