Does Thyroid Cause Grey Hair?

Thyroid dysfunction, particularly hypothyroidism (underactive thyroid), is associated with a variety of symptoms, but there is no direct evidence to suggest that it causes gray hair. Gray hair is primarily a result of aging, and it occurs when the pigment-producing cells in hair follicles gradually decrease their activity. Genetics, hormonal changes, and environmental factors also play a role in the graying process.

In cases where thyroid dysfunction leads to changes in hair color, it is more likely due to the indirect effects of imbalanced hormones on the overall health of the hair follicles. For example, severe hypothyroidism can lead to hair loss (not necessarily graying) as a result of changes in the hair growth cycle.

If you are experiencing concerns about your thyroid function or changes in hair color, it’s essential to consult with a healthcare professional. They can conduct tests to assess thyroid function and provide guidance on managing any underlying thyroid issues. Additionally, discussing concerns about hair health and color with a dermatologist may be beneficial.
