Clearing your scalp of excess product can help boost your hair’s volume. I suggest going for a professional scalp treatment from time to time. It's easier to go to a professional as they can determine the condition of your scalp and recommend the proper treatment.
However, if you want an at home remedy: combine one tablespoon each of lemon juice and vinegar with your shampoo, massage the combo into your scalp, and leave it for five minutes.
