Growing long hair is easy when you're young. That's because your hair hasn't yet been damaged by styling or coloring. Hormonal changes can also impact hair's health, but long hair can be had at any age with a little patience. Your hair must be as healthy as possible, and split ends have to go, so chop it off first if your hair is in bad shape. Then forget about using heat producing appliances, riding in convertibles, racing a brush through your hair, wearing accessories that pinch, pull or break. Don't smoke, drink in moderation, eat a varied diet and take vitamins, especially B12. Use weekly deep conditioning treatments, and long steady brush strokes to transfer natural hair oils from scalp to ends. It's a long process, but if long hair is your goal, you can have it.
