- Semi Permanent Hair Color - Ammonia Free - 100% Vegan & Cruelty-Free

 Introducing Toxic UV! This semi-permanent neon green hair dye looks as deadly as it sounds. This shade glows in both natural light and blacklight. To achieve optimal results, we recommend that you lift your hair to level 9 or 10 (blonde) before use.

Do not mix with peroxide. To ensure the colour is as expected, test on a small swatch before application. For best results apply to pre-lightened / bleached hair. Directions: After shampooing, towel dry hair and apply Crazy Color® evenly over hair (wear gloves). Leave for 15-30 minutes, then rinse thoroughly.
