Oils play an important role in protecting hair from heat and sun. All Franch Herbal Hair Oil formulation is a new and revolutionary ‘pre-wash’ scalp and hair treatment. This unique hair oil is specially formulated to absorb into the scalp within 20 minutes after application. After 20 minutes you may wash off with Franch Herbal Shampoo, leaving your hair non-sticky and oil free. For best results wear a shower cap during the 20 minutes.
