BEFORE & AFTERS

Level 10

The perfect base for the most vibrant and long-lasting results!

Level 9

Kowabunga can easily cover the yellow tones present in level 9 hair. 

Level 8

Kowabunga can be used on any level 7+ blonde hair that has yellow tones. The yellow tones in the hair will not affect green hair color.

Level 7

Kowabunga may add a slight greenish tint to level 7 hair, and will wash out faster.


  1. To create the best blank canvas for your color, we recommend that you first lighten your hair with our easy-to-use GDY Lightening Kit. Our semi-perms work best over pre-lightened hair, levels 7-10. Please refer to individual colors for the best starting level.

  2. Squeeze your color into a plastic bowl. Remember: wear gloves to prevent staining on your hands.

  3. Do a strand test before applying the color all over your hair to ensure you love the look.

  4. Divide your hair into 4 equal sections and apply dye directly onto dry hair with a color brush or your fingers. Make sure the color is fully saturated throughout each section by applying a dollop of color for every two inch portion of your hair. Gently emulsify/massage into the hair to ensure coverage.

  5. Let the color sit on your hair for at least 30 minutes.

  6. Rinse with cool water.

  • To maximize the vibrancy of your newly semi-permanent dyed hair, we recommend waiting at least 24 hours before your first shampoo. To minimize fading over time, rinse your hair with cool water each time you wash. Also, try reducing your hair washing days to extend the color even further.
  • Kowabunga is a true green, so when you rinse your hair, the water will run more yellow rather than blue.
