How To Use Pro Tips Ingredients

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.
Squeeze your color into a plastic bowl. Remember: wear gloves to prevent staining on your hands.
Do a strand test before applying the color all over your hair to ensure you love the look.
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.
Let the color sit on your hair for at least 30 minutes.
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.
Killswitch is a steel metal, blue-based grey color that will fade to a blue color.
Even though this is a darker color, it is important to pre-lighten the hair to a level 10 blonde to show the true grey color.
Depending on how often you wash your hair, Killswitch will last anywhere from 4-6 weeks.

Reviews

Great color

"My husband has been wanting to dye his hair for a while. We had his sister and sil use good dye young's lightener and then the dye. They didn't put enough so when we got home I helped put more on. Now it's beautiful. It's definitely the right color and it didn't burn him. Definitely going to use this for me next"

— Cassandra M. (5/5)

"Color did not stay in my hair, literally lathered 2 whole bottles on my head and only half of my hair picked up the dye. Might be a problem with my hair and not the product itself, but I was disappointed washing the dye out and seeing only half of it took and I had random spots that had no coloring at all."

— Montana (3/5)

Killswitch is nice

"It’s good, thick as a hair mask, the color could be more intense, I put a few drops of None More black and gets better. Nice for toning gray hair"

— MAYRA P. (5/5)

Really good for mixing other

"Really good for mixing other colors in and making another color. People love my color a k about it all the time. The vegan clean dye has made my hair healthier."

— Joice B. (4/5)

"Nice scent, but Really thick. Was a bit hard to squeeze from the tube and took a lot more effort to apply. Other than that, good product"

— s (3/5)

pretty

"i only used this shade on my tips but it was so beautiful and faded to a nice color."

— Angel (5/5)

"Amazing color! ❤️‍🔥❤️‍🔥❤️‍🔥"

— Caroline (5/5)

does not work on level 7 hair

"wanted to use this on my dark blonde hair to make it darker and it did absolutely nothing. I should not have to bleach my hair to make it look darker than it naturally is. Texture of dye is hard to work with as well, wasted more than an hour putting this on just for nothing to happen. This brand used to be so good when I used it a few years ago, quality has obviously tanked while prices went up. Its pretty sad"

— Adrian (1/5)

Is it semi-permanent?

"I take pretty great care of my colored hair but I will say the dyes I have tried (devils ivy, purple ppl eater, rock lobster, killswitch) REALLY grip on to the hair. I am a DIYer, so I love how affordable it is. I am not complaining, I’m saying I’m never going to use another dye again. It also has upped my bleaching technique! So, it’s a win."

— Aimee B. (5/5)

not perfect but a good gray

"super super thick and a little hard to work with color did not look as dark as in the preview photos by a shade or so but smells good and worked out well enough (used it on my ends and roots here)"

— Greyson B. (3/5)
