Revlon Nutritive Serum. Softens, smooths, controls and seals the cuticle of dry, frizzy, rebellious hair. Leaves hair disciplined, manageable, loose and shiny. Rub 1 to 2 pumps of the product between hands, apply onto wet hair and work first onto ends and then into lengths. Proceed to brushing. Finish by smoothing hands over dry hair with one or two drops.
