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.
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 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.

I had my hair lifted to around a Level 8/9 and was delighted to see my hair came out the colour advertised. Of course it wasn’t as light, but that was because my hair wasn’t a Level 10.

this color is so beautiful!! it’s definitely lighter than the promo pics but i’m still in love with the end result, and some of my hair is not lifted to a level 9/10 yet. it can get tricky if your hair has any brassiness or yellow bits in it since this is a pastel shade but i plan to lift my hair more in the coming weeks and expect it to take perfectly. i got the best results saturating my hair with the color and leaving it in for at least an hour!
Jackie from GDY –
Hi Madeline,
Thanks for your review! I’m glad you are loving the color! In order for the Wondermint color to show its truest, it does need to be on Level 10 (platinum blonde) hair. Once you lift to the level I think you will be even happier with the results.

I’ve been using blue ruin or ppl eater for the last year and I always said I thought green would be the one color I never dyed my hair, but I thought I had to try it when they released this shade! I have a buzzed head and had lightened and toned it to a pretty icy white beforehand. It turned out a really nice bright almost leafy green (without looking neon), not as blue as the model but I still really liked it! It’s been almost two weeks and it’s still hanging on waaaaay more than I thought it would for a pastel. I definitely recommend it!

I was so excited to try this dye, but I had issues with my roots coming out a mucky yellowish color. I went to a professional hair stylist, we followed the directions (hair was the right level, used the lightening product from this site) – the top is a BEAUTIFUL minty color, but very sad about my roots. I’d like to try a re-do with the dye, so I think I’ll try one more time and come back with a final review. Fingers crossed because I want to love this dye!

Thank you for your review on Wondermint! We are sorry you didn’t love your experience using GDY. You may need to lighten the roots one more time to get a light enough base for Wondermint to show up true to color. Feel free to send us photos to [email protected] so we can get a better understanding of what’s going on!

I really like this color. I originally had people eater and narwhal in so I expected this to turn out a little more blue than minty. I did lighten it first (I have dark brown hair normally so roots are always an issue) and I was pleasantly surprised that parts ended up with more of the minty tone. I’ve gotten more compliments on this color than any other color I have used so far. Day 10 and it still looks just as vibrant as the day I did it.

Ah yay! This is what we like to hear. I’m so glad you are still rocking a vibrant mint color. Thanks for the review.

Great dye I had bleached hair that grew out a lot so I figured why not add some dye and I stan Hayley so I decided GDY would be cool and it looks awesome I love the mint green and I was afraid of it looking weird on me because I’m pale but it doesn’t make me look sickly and my hair feels soft punctuation? We don’t know her.

I purchased Wondermint with such high hopes! I have been a customer for a while now, and have used all of the original shades (except for ex-girl) prior to this. Firstly, I lifted my roots to a nice white blond (and got the rest of my hair which previously had narwhal and kowabunga in it, lightened as much as possible.) When I found Wondermint available, I loved the mint color of it! Boy was I disappointed when the color turned out to be just a slightly lighter version of narwhal. Everything on the website implied it to be a nice bright mint green, but it was a mid-light aqua, definitely not what was advertised. On top of that, the dye did not take to my hair AT ALL which is very unlike the way any other GDY color has worked on my hair. My roots are a brassy color with a gross green/yellow tone, and the rest of my hair is exactly as it had been pre-application of Wondermint. I left it on my head for over an hour. Overall I would love this shade, but unfortunately the execution was poor, at least, in my experience. I plan on purchasing some blue ruin/narwhal just to fix the color that happened post-Wondermint.
Becca from GDY –
Hi Reagan!
So sorry you didn’t love your experience using GDY. In order for Wondermint to show up properly, the hair should be a level 10 platinum blonde with little to no yellow tones in the hair. The dye may also appear more on the blue side in the tube, but when it washes out of the hair it is the mint color! I sent you a follow up email, please feel free to reach out with any questions!

This color is SO perfect and amazing!! I bought this color to create a split dyed ombré effect along with Wondermint, Kowabunga and Blue Ruin.
Wondermint turned out to be such a beautiful green-teal shade on my hair. It looks very similar to the photos on the website if you have level 9-10 hair like I do. I would definitely buy this again.

Hi There!
I am so glad you loved our new color. Totally agree! If your hair is lifted to a level 10 then our lighter daze line is perfect for you.

Hot dang! The green is so pretty. Parts or my hair really took the blue hue so it came out like a lovely mermaid look. Smells great and my hair felt super nourished when finished up

Hi Jamie,
Glad to hear you had great smelling nourished green hair after using Wondermint. Thanks for the review.

I bought this dye and the lightning kit the day the lighter daze collection came out and I had bleached and dyed my hair and let’s just say I’m disappointed. My hair was between a level 9-10 and when I washed my hair out with cold water after and hour of letting it sit on my head it looked like my hair had been 3 weeks faded. I’m so disappointed because I love this company to bits and have heard such good things bout their hair dye but the dye just completely didn’t make a dent to my hair. If one of the staff of GDY could reach out to me and help me with my issue it would be greatly appreciated.
