Thyroid-related hair loss usually looks like diffuse thinning rather than a few bald patches, so the hair may seem overall less dense , the part may look wider, and the pony tail can feel thinner. It’s also common for hair to become dry, coarse, brittle, or more prone to breakage , and some people notice more shedding when brushing or washing.

What it may look like

  • Even thinning across the scalp , not just one spot.
  • More hair in the shower, brush, or pillow.
  • Smaller ponytail or more visible scalp.
  • Dry, dull, brittle strands that break easily.

Other clues

Thyroid hair loss can also come with other body-wide symptoms, like fatigue, weight changes, dry skin, constipation, or feeling cold when the thyroid is underactive. Hair loss may also affect eyebrows or other body hair in some cases.

When to get checked

If the shedding is new, persistent, or happening with thyroid-type symptoms , it’s worth seeing a clinician for thyroid testing and a hair-loss evaluation. Thyroid-related hair changes are often linked to hormone imbalance and may improve once the underlying thyroid issue is treated.
