When using the L'Oréal Vitamino Color protecting products, start with applying the shampoo first. Wet your hair and apply the shampoo, focusing on the roots and scalp. Massage your hair gently and thoroughly rinse it with water. Depending on the level of hydration needed for your hair, use the mask. Apply the mask to your hair's mid-lengths and ends and keep it on for a few minutes before rinsing. Use the mask instead of the ordinary conditioner once a week for deep conditioning your hair.
