I get 1000 mg of MSM in the Solgar Skin, Nails and Hair formula I take. After this is all gone, I'm going to switch to powdered MSM. The MSM makes my new growth noticibly softer. As far as Essential Fatty Acids, I take both flaxseed and evening primrose oil. The EFAs, or so I've read, helps to moisturize the hair from the inside out.
HTH,
