Moisten hair and scalp thoroughly with water. Apply sufficient shampoo to produce enough lather to wash the scalp and hair and gently massage it over the entire scalp area for approximately 1 min. Rinse the hair thoroughly with warm water. Repeat, leaving the shampoo on the scalp for an additional 3 min.
After the second thorough rinse, dry the hair with a towel or warm air flow. Shampoo twice a week for 4 weeks with at least 3 days between each shampooing and then intermittently as needed to maintain control.
