The chemicals in the Pre-Wash Primer help to repel water, which is one of the harshest agents for fading hair color.Ingredients like white orchid extract helps to provide moisture, while ingredients like almond oil work to reduce breakage, and coconut oil makes your hair extra soft.Combined, the ingredients in this product work to give you color that lasts up to two times longer than if you didn’t use the Pre-Wash Primer.How It Works:Before you even get into the shower, apply the Pre-Wash Primer to your hair. A barrier will be formed, and water will actually be repelled from your hair’s cuticle, where the hair dye can get attacked by water. Once you’re in the shower, wash with the sister Nexxus shampoo (or any color care shampoo product), and enjoy your vibrant hair color for weeks and weeks
