Using this product is a breeze. First, open the clamshell. Then, apply the metallic hair streaks to your hair where you want the extra sparkle. You can make thin or thick streaks depending on your style. Remember to do a small test on a hidden part of your hair first to check for any allergic reactions. After use, close the clamshell tightly to keep the product fresh. To clean, just wash your hair as you normally would. Store it in a cool, dry place away from direct sunlight to maintain its quality.
