http://www.naturalnews.com/030171_hair_growth_supplements.html(NaturalNews) Diet, aging, stress, disease and genetics all contribute to hair loss, and adding nutrients to the diet can help grow hair. Hormonal imbalances can also lead to hair loss, and women after menopause are particularly at risk. Steroid drugs, or other drugs that interact with hormones, can alter hair growth and cause hair loss as well. A healthy diet can encourage hair to grow. Whole foods and raw foods are the best sources of vitamins and nutrients but adding vitamin supplements can help jump start the regrowth of hair.
