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.

I’m super happy with this dye! The color is so vibrant. My order shipped quickly, and the little single-use shampoo and conditioner were a nice surprise.
The application process was easy, and my hair was super soft after I rinsed and dried it. That was probably my favorite detail–usually after I dye my hair it feels a little dried out and abused. But not with this!
I’m glad I decided to try GDY because after seeing my results with Kowabunga I’m itching to try a whole rainbow of colors next 🙂

I have been using kowabunga (with none more black sometimes mixed in) on my hair for about a year. I love this brand so much! The dye lasts longer than other semi permanent dyes I’ve used (arctic fox dye), and I absolutely love that they’re vegan and cruelty free! I recently bought a bottle of kowabunga online to refresh my color. I am used to buying this dye in stores but due to the corona virus and social distancing, I opted for online. I was pleasantly surprised to find one time use shampoo and conditioner packets! That’s what actually prompted this review! Anyways, I love this brand and will continue to buy from them as long as I decide to color my hair!

I LOVE this color. Did my hair two toned with Kowabunga and Ex-Girl, and the blue undertones adds the perfect amount of tone to the green. My new favorite GDY color by far!

i haven’t even rinsed it out yet and im already in love with the color!! I shaved my head recently and i didn’t need to use too much dye so it’s convenient that i can cap the dye and keep it for touch ups!!
Jackie from GDY –
Hi Ema,
So glad to hear you love the color! In addition to using it for touch ups I also suggest mixing it with your conditioner to create a color deposition conditioner to keep your color fresh. Our hair expert Becca made a YouTube video on it, check it out on our page.

Kowabunga is by far the best green dye I’ve used! After using the Lightning Kit I had some very light parts and some medium parts (my hair had grown out after being dyed black, I consider the amount of lift quite good) and applied the green. The very light hair is a bold and bright green (nice!) and the darker hair is a lovely emerald with some lighter parts throughout. Overall wonderful experience, it smells SO GOOD.

Hi There!
Yes, green queen! So glad you are loving Kowabunga. Im sure you hair looks AWESOME! Happy to hear your had a wonderful experience.

This is definitely the best hair dye formula I have found for my hair. I am naturally blonde, and I prefer not to bleach where possible, and this dye stains my hair so well and fades so beautifully that other hair dyes seriously don’t compare. Not to mention I have to purchase it much less frequently because of how well it stays in my hair. I recommend GDY to everyone who asks me for hair dyeing advice just because it’s so ****** good.

Hi There!
I am so glad to hear you are loving the green dye! We packed it with pigment so you don’t have to dye as often.

I’ve used this since it came out and it is super bright and lasts forever! I always bleach my roots and dye it green and I love that it glows in blacklight! I’ll keep buying it again and again.

This is a very late review, but I purchased this dye back in October of 2019. This was my first time going green and until January 31st of 2020 the green was STILL in my hair.
This is a pro and con, but this color does last. To me, I think it even fades to a nice pale green, which is a huge plus in my book. As I like to give my hair breaks from the bleaching and dying, this is a color I would recommend for how long it keeps.

(i’ve used this product before and it’s definitely 5 stars) okay just a question so I have black hair, and I wanna dye my hair that emerald green color. Should I use this and add none more black, i don’t really wanna bleach my hair, would this color alone just make my hair that emerald? or should I add a bit of none more black
Becca Sievers –
Hey! Our dyes work best with pre-lightened hair. Unfortunately, semi-permanent dye will not show up on black hair to give you that emerald green. We suggest pre-lightening your hair to about a level 6-7 and then adding Kowabunga with a little bit of None More Black to achieve an emerald green! If you have any other questions, please email us at [email protected]!

I was wanting to try out GDY ever since it came out, and I got the poser paster a little while back. Because it was so good, I saved up a little money and got Kowabunga and I was absolutely AMAZED at the colour. I did a half-blue and green look with Manic Panic for the blue, and GDY outlasted MP over a week!! This is simply the best semi-permanent hair dye I have ever used and will forever be a fan.
p.s. it outlasted the colour I got done the first time professionally (which was also green) and it made my hair feel like heaven.
Hallie from GDY –
Hey!
Thank you so much for giving GDY a go! We’re so pleased that our Kowabunga surpassed your expectations! Our dyes are formulated with sunflower extract and a blend of essential oils which help to condition and strengthen hair while also providing that great scent!

We finally started selling GDY in the Sally’s I work at and I was more then excited to try it out being a huge Paramore fan. It is the BEST semi-permanent color I have ever used! The color is gorgeous and it keeps my hair feeling amazing but, the most important part is the color lasts foreverrr. 1000 out of 10 will recommend to every customer and everyone I know!

Amazing! The $8 shipping still came fast af and oh man the packaging does not disappoint. I did hang it up on my wall. The dye itself is so vibrant, conditioning, and it smells amazing. The coverage is to dye for. I finally am living my Teenage Mutant Ninja Turtles dream. Gonna go get some pizza now.

Green is my new favorite color!
I added just a touch of None More Black, as my hair is slightly warm toned, and the color is so vibrant and intense! Because I’m extra, I’ve got a spot in my bangs that is straight Kowabunga sans NMB, and it’s so beautiful and insanely vibrant! I recolor every two weeks to keep it super bright, though I’m positive I could get away with waiting longer between applications. It applies like a dream and smells absolutely fantastic. Totally recommend!

I had previously lightened hair and wanted to do something new. I started with a mix of Narwhal and Blue Ruin but the next day used the lightening kit and then Kowabunga. The next day I used some None More Black to create some dimension and had an awesome emerald green going on. I called it “From The Edge of The Deep Green Sea” after the song by The Cure. Very pleased with this green color. I also like how you can use it to cancel out the voilet undertones of None More Black.

I have very short hair and one whole bottle was used on mine. I mixed the green with a bit of black to get a much less bright color, I also did not bleach or lighted my hair (it’s naturally an ash blond/light brown) and it was just the color I was going for. It did fade some but after 3 months is still pretty green. I’m going to redye it to make the color more green as well as because my hair has grown out about 2 inches. Anyway I love this dye, I got just the color I wanted with it, it lasted very long, and it smells phenomenal! The first two washes after dyeing the shampoo on my hands was only very slightly green.
