You should wash your hair at least once a week. You should only use conditioner as shampoo strips your hair of its natural oils. If you comb or brush your hair, you should limit it because this can cause your hair to rip out due to the tangles and knots, thus resulting in shorter hair. If you want to comb your hair, make sure you do it in the shower with conditioner. (The water and conditioner helps the comb slide through the hair easier.)
B, hair growth is genetic. It goes between 1/8th to1/4th inches a month. -You need an overall "Wellness Plan" 1. Get a Moleskin Wellness Journal and keep track of your activities. 2.
