Is Whey Protein good for hair?

Actually, whey protein powder can be very good for your hair! Hair is made of a very tough protein called keratin. For your body to make hair grow it needs a good supply of amino acids to build keratin protein. The essential amino acids found in whey protein can be a valuable source. If your diet is protein deficient, then hair health can suffer and even hair loss can occur. Supplementing with whey protein can help provide what your body needs for a more healthy head of hair.
