To understand how the thyroid cause hair loss, we need to understand the connection between the thyroid glands with the hair on our head.
A thyroid gland is aggravated when it produces too many hormones or doesn’t produce them at all. The two conditions are called Hyperthyroidism and Hypothyroidism.
- Hyperthyroidism is the overactive gland that causes side effects like weight loss and anxiety and leads to thyroid problem cause hair loss.
- Hypothyroidism is the underactive gland that causes side effects like weight gain and weakness.
The common condition seen as a side effect in both the stages of the glands is hair thinning and hair loss. Hair tends to become brittle, which leads to split ends and breakage.
