Brush through the entire scalp while hair is dry. This will help remove any build up on the scalp and help blood flow. Next, rinse the entire scalp and hair thoroughly with warm water to remove loose build up. Apply the pre-cleanser through the nozzle directly onto the scalp. Starting from the hairline at the top of the scalp, use your fingertips (avoid using finger nails) to massage in an upward motion working your way throughout the head. Massage your scalp for 2 minutes. Rinse thoroughly. Proceed with NEKKO Head Spa Shampoo and your conditioner.
