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.
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.

Giving it four stars because I absolutely LOVE how the dye makes my hair feel (so so soft, and it smells great), but you need to believe the reviews when they say the color bleeds SO much. I dyed my hair over two weeks ago and the dye is still coming out on my clothes/pillow case/and actually on my WALLS because I leaned against them. I’ve washed my hair strictly with *cold* water to try to keep the color in, but that only does so much. This color is excellent for the color that it is, but it’s getting four stars because all of my stuff is dyed blue! 🙁

Hi Emily,
We’re so glad you love Blue Ruin! We pack pigments into our dyes to ensure long lasting color and that can result in temporary bleeding of the hair color.

This is such a beautiful blue! I love how vibrant it is. I would recommend this brand in this shade to anyone!
My only complaint is how much is bleeds and stains, but I find that blue is the only color that leaks as it does.
Jackie from GDY –
Hello!
Thanks for your review on Blue Ruin. I am so glad you love the color We pride ourselves on packing our colors with pigment so they are vibrant, which is why it may bleed a bit during your wash.

it really pains me to give this product such a bad review because i adore this line of dye. but the stains the dye leaves are insane. i usually split my hair in half and dye each side a different colour. last time i used the yellow and green dye and it turned out beautifully! but when i covered the green with this blue, my entire yellow side turned green. it looks terrible now. i’m really disappointed. i know many dyes bleed quite badly but no other colour from this line has bled this badly for me. it majorly stained my bathtub, my skin, my clothes, my floors, my linens, and anything the dye came in contact with. the colour is lovely but i definitely won’t be using it again due to the excessive bleeding :(((

I absolutely love this color and the product is fantastic. The dye smells great and my hair feels sooo soft but listen to the reviews when they say the color bleeds. My hands, face, and tub are blue. Honestly I’ll probably just buy a different color bet time and hope it doesn’t bleed as bad. If it didn’t bleed as bad I’d give it a 5/5, regardless this is probably my favorite dye that I’ve tried so far!

Hi Elizabeth!
We’re so happy you love our Blue Ruin as much as we do! That amazing scent is made up of our special essential oil blend consisting of Bergamot and Citrus. Our dyes are heavily pigmented and do tend to bleed but you can minimize this by washing your hair sparsely and in cool/cold water when you do wash. This helps to seal the color into the hair cuticle and help your hair stay soft and shiny while minimizing bleeding.
Thank you for reviewing our Blue Ruin!

The color is amazing! Such a vibrant Blue. I have used many different brands in the past, and this color seems to hold on the best. WARNING: color bleeds extremely bad, if you keep your hands in your hair, YOUR HANDS WILL BE BLUE (EVEN WEEKS LATER), AND IT WILL LOOK AS IF YOU HAVE MASSSACRED A VILLAGE OF SMURFS…

i tried this dye because i love hayley williams with my whole heart, but this dye is driving me insane. its been about 2 months since ive dyed my hair and it will not come out. the past week ive tried every semiperm removal method but this wont budge. normally this would be a good thing i suppose but i wanted semi perm and not this to be stuck forever. i really want to dye my hair red, but now its too blueish green

Hi!
This was my first time dyeing my hair a vibrant color (I went platinum blonde once). I did it all on my own and while that made me nervous, I kind of had a blast. The color is super pigmented, so I would DEFINITELY recommend some disposable gloves so your hands don’t turn blue. The color stays, but when I was it kind of fades to a lighter blue. I love the deep, vibrant blue when it looks freshly-dyed, so I touch it up by putting a little dye in my conditioner about once a week-ish? With gloves; I’ve stained my hands blue a lot! And my tub a little bit, but I’ve managed to scrub it out.
Also, I feel like everyone says it smells awesome but they aren’t kidding!
Thanks GDY!

Alright, so I’ve dyed my hair a lot, every color imaginable. So I decided to go blue one day on a whim and went to Sally’s and they pitched me this new brand that had just been released, Good Dye Young. I’ve never met Haley Williams, but honestly I would trust her with my life, so I said sure why not. First of all, the dye smells AMAZING. A little went a long way, and although I only had time to leave the dye in for 20 min, it sure was BLUE. There were a few spots where it didn’t take as well and ended up kind of green, which is my least favorite hair color, but we touched it up later and left it in longer. I live in A place where the water is harsh, and I didn’t use color safe shampoo, so it did quickly fade, but dang, that color holds on. I dyed it in January. It is now August. I’m still green. I’ve tried color oops, bleach, vinegar, heat, nothing has worked. The only ting that came close to working was dying it red to neutralize it, but that quickly faded to, guess what, green again. I personally hate having green hair, but this is my life now. I’m one with the green. I’m basically Shrek, but like, hotter. Moral of the story, if you’re going to use this dye, you gotta COMMIT, cuz it ain’t givin up on you easy.

Color payoff is great. The staining is a disaster. If I wanted a color that stained this much I would just use splat. Probably wouldn’t buy again unless the formula was changed.
Becca Sievers –
Thank you for your review on Blue Ruin! We are happy that you like the color payoff. Our colors are extremely pigmented to give you the longest lasting results. Sometimes this can mean more bleeding. However, the color will stop bleeding after a few washes!

THE BEST! Blue ruin has such a beautiful and bright pigment and smells so good! I get compliments on my hair color all the time! I found that maybe $18 for the tube is a bit much, but the product does last a long while since you only need so much to get to the desired color you want. The color fades well and last me weeks before ever having to touch it up. I also used the lightening kit that I bought from Sally’s and it worked great, but since I have pretty long hair I needed more than one kit. I will definitely only be using this brand for hair dyes. Also, I love that the products are vegan and cruelty free! ily GDY ?

I know it says the color lasts 4-6 weeks , but for me personally it lastes MONTHS! and i wash my hair very frecuently so i was So impressed. I bought this color twice and is the best dye i ever used.
P.S: i think the fluid ounces changed because now i can use only 1 box of dye for all of my hair!

This dye is fantastic! I mixed it with half a tube of PPL Eater to get a rich indigo color. It’s held up extremely well! It’s been over a month since I dyed my hair and the color has only faded a bit. It has bled onto my clothes, however it comes off in the washer so it hasn’t stained anything. Though it does bleed quite a bit. Other than that, this dye is amazing and I will definitely repurchase it in the future!

Blue ruin is THE dye for me. I LOVE how blue it is and how it always lasts soo long. So I am so glad for that. I’ve been using Blue Ruin since the end of 2016. Having blue hair makes me feel soo confident. I love how it fades to a beautiful aqua then a nice green. I will continue to dye my hair with GDY. I recently ordered some more Blue Ruin and a box of PPL Eater. So at some point I will try out PPL Eater. P.S. I LOOOVE how it smells. ♡♡

This blue dye is great!!! I’ve had it in my hair for about 2 months and although it has faded, it’s faded SO WELL! I went to my moms the other day and she just said “your hair is REALLY still THAT blue” it’s the magic of GDY, mom ?♀️ 10/10 recommend this to EVERYONE!!!!

I have no words for this product. I used to use Arctic Fox but it kept fading too quickly and then I found this and my mind is blown! I had a very washed out blue to start and now I’m a vibrant dark blue and I LOVE it!! I bought the hair care as well and just using the prewash, shampoo and conditioner just today I noticed an amazing change in my hair. Best of all? The color is STILL there! It hardly faded (if it did) whereas my first wash with other brands would practically fade to pastel almost.
Finding this brand has been a godsend!! I get so many compliments at work with it and though it does stain I can deal with that because I am absolutely in love! Finally, I found vegan hair colors and hair care that works and smells absolutely wonderful!! I’m so pleased and shall go “dye happy” now!♡♡

Hi, hello!!! I bought this color around January and I only used less than half the bottle bc only half of my hair was “dye-able” but anyways I still have some bc I’ve only touched up once!! The color is still strong and beautiful!!! And when it fades it’s a cool green-blue and at work (I’m a cashier at a grocery store) I am constantly getting complimented by customers with the fresh and fading versions!! I recommend you guys to EVERY customer!! Anyways thanks for being the first hair dye brand to not suffocate me!!! ?

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.
Hallie from GDY –
Hey!
We are so happy your hair is very vibrant and has lasted for a long time! You are correct in that our Blue Ruin is more of a deep blue but the more you wash your hair (especially in hot water), the more your hair will fade to a lighter blue! If there’s anything else we can help you with, please let us know!
