Step 1: To create the best canvas for your color, we recommend lightening your hair using our GDY Lightening Kit. Semi-permanent dye shows up best on level 10 light blonde hair.

Step 2: Squeeze your color into the GDY Biodegradable Tool Kit. Wear gloves to prevent staining hands!

Step 3: Do a strand test before applying the color all over to ensure you love the look!

Step 4: Divide your hair into 4 equal sections and apply dye directly onto dry hair. Make sure the color is fully saturated!

Step 5: Let the color sit for at least 30 minutes.

Step 6: Rinse with cool water, no shampoo or conditioner required! Style as desired, u hottie ????

Allow at least 24 hours before your first shampoo.

Rinse hair with cool water each time you wash to minimize fading process.

Reduce hair washing days to extend color.

This blue dye is highly pigmented, giving you long lasting color that will fade into a lighter blue over time.

Not feeling that sort of commitment? Try our pastel version of blue, Sky High!

Blue Ruin will add a tint to darker hair and show up vividly on level 7+ hair

Blue Ruin tends to bleed the most out of all of our dyes. We suggest shampooing it thoroughly after dyeing to remove the excess pigment from the hair.

Don’t worry, that color isn’t going anywhere!
