Shampoo your hair every other day or every third day. Shampooing daily can also be damaging to your hair. When you shampoo, you strip the natural oils from your hair causing the hair to be more brittle. If your hair is already damaged make sure when you do shampoo you use a moisturizing shampoo or one especially for damaged hair.
