Hair cannot be grown "fast" naturally. There are plenty of so-called pills and potions available in the market that claim to help you in your endeavor but the results and side-effects of most of these are questionable. Natural means to growing hair will includes a protein (eggs, lean meat, lentils), vitamins(fresh fruits) and mineral (green leafy vegetables) rich diet, regular shampooing and washing, very little or no blow drying .
