What does it do?

Our semi-permanent hair dye line combines salon-grade pigments with a nontoxic, conditioning formula that deposits ultra vibrant color. Semi-permanent hair dyes do not damage the hair, in fact they’re super conditioning! GDY’s formula combines a high-quality cream base, like a hair mask with essential oil benefits. The color is deposited on top of the hair shaft and acts like a stain that will fade out over time each time you wash your hair. Color can last anywhere from 4-6 weeks. We recommend using color protecting hair care like our GDY Color Kind Line to keep color vibrant longer.

What does it smell like?
Fragranced with Bergamot essential oil, our semi-permanent dye has a light citrus scent that is mood lifting.

Is this for my hair?

Our semi-permanent dyes will show the truest color on pre-lightened hair, levels 8-10. We recommend using our Lightening Kit to get the perfect base shade for your color.

What to know?
Semi-perm is a thick, conditioning formula, no need to mix with a conditioner.
Color payoff will vary based how much hair is lightened as well as on the porosity of the hair and underlying hair chemistry. We recommend a hair strand test to determine color payoff.

Safe on:
All hair textures, pre lightened, chemically treated, keratin treated, and color treated hair.

  • Healthy hair focused, no PPDs, Ammonia, Sulfates, Parabens or other harsh for hair chemicals or additives.
  • Sunflower Extract adds extra UV protection from the sun and hot tools that fade hair.
  • Fragranced with essential oil Bergamot, known for its mood-lifting properties.
  • Ultra creamy formula that deeply conditions while depositing color.

  • All of our products are vegan and cruelty free
  • Step 1: To create the best canvas for your color, we recommend lightening your hair using our GDY Lightening Kit.
  • Step 2: Mix color in the GDY Color Mixing Bowl and use gloves to prevent staining hands.
  • Step 3: Ensure you strand test first before applying color all over your head.
  • Step 4: Section and apply directly onto dry hair. Make sure color is fully saturated at every step by combining product through each section.
  • Step 5: Let the color sit for at least 30 minutes.
  • Step 6: Rinse with cold water and style as desired with GDY Prime.

  • 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.


  • While color is processing, use a cap to keep the color damp.
  • Coloring your hair is an investment. Make sure to use color protecting hair care like GDY’s Color Kind Line to keep color vibrant longer.
  • Product will stain, so protect hands, all surfaces and clothing.
  • Apply shea butter, coconut oil or thick conditioner to the hairline to prevent staining.
  • Check out our FAQ’s for more information
  • 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? Cut the pigment load by mixing in Fader, or 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!
  • Add a few drops of None More Black to create a Navy Blue!

    I gotta say, I am in LOVE with the color. Definitely what I was looking for. The only problem is the bleed. Be ready to have a blue shower, blue sink, blue neck and blue hands. Four days after, still loving the color on the hair not much everywhere else. (Bleach is helping with removing the blue from everywhere else. )

    This colour is great, I mixed it with Narwhal and got a really nice blue. However, like people have said in previous reviews… it bleeds a lot. Other GDY colours do not bleed this much. It doesn’t just get all over my bathtub. It’s on my clothes, pillowcases, and hands every time I do my hair. This has seemed to subside a bit after two washes, but beware for the first while you will have blue on everything. I noticed a GDY team member has replied to a lot of reviews saying “our products are packed with pigment, the bleeding will get better after a few washes” which is true, but how come this colour bleeds so much more compared to the others? A formula change to correct that would be great for this particular product.

      Hi There!

      Thanks for your review. Yes as you said our products are packed with pigment, the bleeding will get better after a few washes. It happens more often with our darker colors like blue, because they are a richer deeper pigment that likes to hangout in your hair. Which is great for vibrancy, but like you said does cause it to bleed a little more.

    While it’s a beautiful color and it leaves your hair soft and smelling nice, it does stain EVERYTHING. I colored my hair with blue ruin back in feb and it’s still in my hair, no touch up and I’ve tried bleaching twice and once with the good dye young lighter and it won’t budge. Normally this wouldn’t be an issue but I am someone who likes to change their hair color every 2-3 months….I’m afraid I’m going to permanately damage my hair because I can’t get this color out

      Hi Bianca,

      We pack our dye with pigment so you can have that lasting color. However, sometimes you want to change to color before it leaves. Reach out to our hair expert Becca at she can help you come up with a plan to remove the color and protect your hair.

    I have used a lot of dyes and I love Blue Ruin! It is such a strong, pigmented color. I mixed Blue Ruin with Steal My Sunshine to make a more blue based green last summer and I didn’t have to fight fading much at all. In fact, when I had to dye my hair before school started back (I’m a teacher) I actually had to work to make it fade so the green didn’t show through in the undertone. The other wonderful thing about Blue Ruin is the ability it has to overcome spotty undertones from previously dyed hair. It is a great color if you are in the process of shifting from warm to cool toned hair! I also love that it stays on hair, not on surfaces! I have found that on non-porous surfaces such as tubs and sinks, if you quickly attend to drops/stains with cold water and a soap based cleaner, it doesn’t leave a set stain. This requires some diligence on your part, but there are other brands that are MUCH harder to keep from staining surfaces.

    Love Good Dye Young!

    BEAUTIFUL BLUE!! i had to bleach my hair (used GDY kit) and this blue dye turned my hair into a beautiful sky blue. only thing i have to say is, it stains everywhere in the shower which is expected with such a pigmented dye

    • Jackie from GDY

      Hi there!

      Im glad you love your new hair color. As you said our dyes are packed with pigment, which can cause them to bleed for a bit. After a few washes it should lessen.
