what does thyroid hair loss look like

Thyroid hair loss often looks like a general thinning across your scalp or eyebrows, and it might develop slowly. Patients with hypothyroidism or hyperthyroidism notice a gradual thinning of their hair rather than localized bald spots or missing patches. Hair loss is a very common symptom of a thyroid imbalance, and it can cause overall thinning or bald patches. The loss is diffuse and involves the entire scalp rather than specific areas. If you’re brushing through your hair and notice chunks of hair leaving with each stroke, it might be time to get tested for a thyroid condition. Both hypothyroidism and hyperthyroidism can cause hair to fall out, and in most cases, the hair will grow back once the thyroid disorder is treated.
