You can grow stronger and faster if you take good care of your hair. For example, don't tie your hair when you sleep at night, avoid exposure to the sun, don't wipe it hard with a towel after washing your hair, and don't sleep with wet hair. I really don't know what to eat. But eating walnuts can make your hair black. If you tighten the skin behind your back, do exercise, lie on the bed, straighten your hands and feet, then lift your hands and feet at the same time, stop at the highest point for 3 seconds, then put it down and repeat. You can see the effect for a long time.
