    Amazing vibrant and long lasting blue! I’ve had it this color for a month with minimal fading. Smells amazing and made my hair softer! 🙂

    My only criticism is that I warn users that the dye color is more of a deep royal blue when dyed on white/platinum blonde. To get the color advertised on both models pictured above you need to add a large amount of fader.

    A wonderful blue that last long and fades well! Smells great too!

      We agree that Blue Ruin is a wonderful blue and we’re so happy that you love it too! That great smell comes from Bergamot essential oil which helps to condition hair and also helps to alleviate stress.
      If there’s anything else we can help you out with, please let us know!
      xx dye happy,

From day one, Brian and I listed Clementine from the movie Eternal Sunshine Of The Spotless Mind as an inspiration for some of our shades. When her character is first introduced, she talks mostly of her hair, which is dyed – rather unevenly, haha – a bold blue… “It’s called ‘Blue Ruin’. Snappy name right?” – Hayley

1. To create the best canvas for your color, we recommend lightening your hair. Use our Lightening Kit and follow the directions to achieve the correct foundation for your color.
2. Mix color in the GDY Color Mixing Bowl and use the GDY gloves to prevent staining hands. (see GDY Tool Kit)
3. Do a strand test to insure color is as desired.
4. Section out dry hair and apply the color. Make sure color is fully saturated at every step.
5. Let the color sit for at least 30 minutes – the longer you let it sit, the more vibrant the color.
6. Rinse with cold water, gently dry your hair and style as desired.


  • Apply shea butter, coconut oil or thick conditioner to the hairline to prevent staining.
  • While color is processing, use a cap to keep the color damp.
  • Product will stain, so protect all surfaces and clothing.
  • Rinse with our Fader to minimize bleeding of the color.
  • Allow at least 24 hours before your first shampoo.


  • The more you wash your hair, the more your color will fade. Rinse with cool water when you do shampoo…as cold as you can stand if you’re up for it!
  • Use Conditioning treatments! You can actually use our Fader as a hair mask! Leave it in for 10-15 minutes for softer hair.
  • Save leftover dye to touch ups roots when they come in. Simply seal up your unused portion and store in a cool, dry place. The product will last up to 12 months after opened.
  • Add a few drops of your GDY Dye into your shampoo and/or conditioner to keep the color bright.
