When we think of hair care products, we don't typically think of iodine but it's needed to grow hair and if you don't have enough, it can cause your hair loss and thinning.
The growth of hair follicles is controlled by your thyroid hormones which are developed in a butterfly-shaped gland that is located at the front of your neck called the thyroid gland. Iodine is the primary ingredient in the creation of the thyroid hormone which actually stimulates the growth of new hair. (1)
