Keratin Infused Deep Conditioning Masque is an intense, nourishing and hydrating treatment that revies hair that has been dried or damaged by the environment or styling stresses. Jojoba, Walnut and chestnut oils penetrate deeply into the hair, resulting in unparalleled moisture, strength, elasticity and brilliant shine. INSTRUCTIONS: Use once a week to repair and hydrate hair. After shampooing, apply masque generously to wet hair from roots to ends, comb through and leave in for at least 3-5 minutes. Rinse well. To intensify results, cover with plastic cap and process with medium heat dryer for up to 30 minutes.
