2. Apple Cider Vinegar
If you do not want to spend extra on a clarifying shampoo, the next best thing is to use apple cider vinegar. Mix one-half cup of apple cider vinegar in one cup of water and use this as your final rinse after shampooing your hair. Leave is on for at least three minutes before you rinse your hair in cool water. Once a week of apple cider vinegar treatment will clean your scalp and stimulate hair growth.
