First, you should wet your hair and rub the shampoo on your palm. Gently run your fingers through your hair and massage your scalp with fingers. Do not scrape the scalp with your nails. It is not necessary to rub your hair intentionally unless you have used a styling product. After washing your hair, apply a towel to dry your hair without rubbing it. Use a scalp toner afterwards, then use a heat-insulating and moisturizing product (OPC Protective Spray and Silk Potion Cream) on your hair, and then blow dry.
