Dampen the entire scalp and hair. Apply the formula from the tube nozzle directly to the scalp in partings approx. 1” (3cm) apart, working from the front of head to the back. Using your finger gently spread the formula down the parted hair line on to the scalp and leave to absorb for 10-20 minutes. Whilst your scalp mask is working, apply Elasticizer to mid-lengths and ends for an extra hair treat. Rinse and follow with a double shampoo, using Philip Kingsley Flaky/Itchy Scalp Shampoo. First shampoo and gently massage for one minute to lift and remove loose flakes. Rinse and shampoo again. Condition hair using the appropriate Philip Kingsley conditioner for your hair type. Finish with Flaky/Itchy Scalp Toner. Use mask once a week. One tube is adequate for one full scalp application.
