Hair loss

Thyroid hormones aid in the regulation of hair follicle development. Hair follicles may cease renewing if your thyroid hormone levels are insufficient. This can lead to hair loss over time. As a result, persons who are deficient in iodine may have hair loss.

According to one research of 700 adults, 30% of those with low thyroid hormone levels reported hair loss. Other studies, however, have indicated that low thyroid hormone levels only appear to promote hair loss in people who have a familial history of hair loss. If you have hair loss due to a lack of iodine, increasing your intake of this mineral may help restore your thyroid hormone levels and halt hair loss.
