If your hormones are being affected by some type of thyroid disease, your whole body can be affected. It can affect your body in many ways, including your weight, mood, and even hair loss. Hair loss is actually a fairly common side effect of thyroid disease, but the good news is that it is not a permanent problem as long as you get the treatment that you need.
Your hair follicles follow a natural hair growth cycle. At any given time, two-thirds of your hair is growing while only one-third of it is resting or transitioning. But any changes that occur in the body can throw off that cycle. This means that too many hairs are resting at one time and not enough are growing. The results are hair loss, thinning hair, and even balding.
