1. When washing your hair, wet your hair thoroughly for 30-60 seconds. 2. Pour some shampoo into the palm of your hand. Spread it between your hands and distribute it evenly through the hair. 3. Gently massage your hair and scalp. Do not rough up the hair or pull long hair up onto the scalp, as this may cause tangles. 4. Massage your scalp with your fingertips. This stimulates blood circulation and is gentler to the hair cuticles. 5. Rinse your hair thoroughly, as poor rinsing can result in dull hair. Finish with a cold rinse for extra shine. Straighteners are powerful styling tools and should always be used with care.
