Depends on cause: There are many causes of thinning hair and some, like hypothyroidism or vitamin deficiency, are reversible. Vitamins needed for healthy hair include b3, b5, b6, b12, biotin ; a, c, d, e ; zinc. While deficiencies can cause hair loss ; taking these may prevent hair loss, they are not proven to restore hair loss in most, but are worth a try.
