I take MSM, ground flax seed and flax oil, vit E and vit C which both improve circulation, and an all B vit. I also condition with orgainic coconut oil. My hair and nails grow very fast. My hair is healthy and shines. I also use a honey rinse off and on. I just add 1 teaspoon of honey to a quart of warm water and pour over my head after shampooing/conditioning. Would recommend a healthy shampoo/conditioner also.(Take your vit C and MSM together.) Maintain a healthy diet. Wishing you great, healthy, hair.
