As an intensive cleansing treatment for dry hair: Massage in generously from the roots to the tips, leave on for 15 minutes and then rinse thoroughly. Follow with Purifying Shampoo for a deep cleanse and Detangling Gelée for a gentle conditioning treatment.Warning: Avoid contact with eyes. In case of contact, rinse thoroughly with water.
