Yes, thyroid problems can cause significant hair loss in both men and women. Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) disrupt the normal hair growth cycle. The thyroid hormones T3 and T4 directly regulate hair follicle function, and imbalances can cause hair to become thin, brittle, and fall out more rapidly than normal. Studies show that up to 50% of people with thyroid disorders experience some degree of hair thinning. The hair loss typically affects the entire scalp rather than creating patchy bald spots, and eyebrow thinning is also common. Fortunately, treating the underlying thyroid condition usually restores normal hair growth within 3-6 months, though full hair recovery may take up to a year.
