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.

Listen, you may be reading these reviews because you’re like I was, worried about how such a bold color will look on you. The way I see it, own it and it will look great. I’ve washed my hair 5 or 6 times and the color has barely budged, it really lasts! It’s such a nice color! If you bleach to a brassy blonde it’s less in your face and so cute but if you want that highlighter feel, get as light as you can. Such a great product with a great smell, do it. I live by this brand, it’s got me back into my hair dying kick and it’s the only brand I will be using from now on.

I’ve used this both on it’s own for yellow hair, and as an additive in Kowabunga to create a swampy green and it’s perfect. It’s very bright and lasts a long time, but also my hair faded to a nice blonde after I stopped dyeing it! It didn’t leave my hair brassy at all.

I absolutely LOVE this color. I always wanted yellow hair but the dye I was using for the last 10 years never seemed to have the yellow last more than 2 washes. I put Steal My Sunshine in over a month ago and it’s just as vibrant as ever.

I really loved the color pay off—-on half my hair. The product smells great and it’s SUPER easy to work with and mix, but it’s not at all consistent. I have very vibrant color on the left half of my head, but near my roots it’s super muddy (almost blonde) and the right side of my head looks like i dyed it a month ago.
I really love the color but unfortunately I don’t know that I could recommend this dye (or that I’d buy it again) because at $18 a tube I can’t afford to buy a whole other tube to touch up the hair that for some reason didn’t take.
For background i had pre bleached my hair to a 9.

Hi! Thank you for your review on Steal My Sunshine. We are so sorry you didn’t love your experience using GDY. In order to get an even color it is important to ensure your hair is lifted evenly. Depending on length and thickness of hair, you may need more than one tube of color. Please reach out to us if you have any questions!

this dye is great – a really nice consistency and smells good but it turned my white blonde bleached hair into like a highlighter green-yellow. i really love the colour in the photos and it seems like many other people have had a positive experience but the colour is not at all what i wanted/expected
Jackie from GDY –
Hi Charlotte,
Thanks for your review on Steal my Sunshine. It will get brighter each time you wash it! Glad to hear you love the consistency and smell of our product. Our dyes are made to be highly pigmented while also being nourishing.

Really confused! I bought steal my sunshine and I have before many times and it looks orange this time around. Not sure if it’s Sally’s Beauty that caused this but it’s definitely riot in a steal my sunshine package. 🙁

BEST SHADE OF YELLOW EVER! been using diff hair dye brands for the last few years, I can say that this is the YELLOW I’ve been looking for! At first, when i opened the bottle and squeezed into my bowl, I was hesitant about the shade because it was too orange-y, but then i still put it into my hair, and yes, it’s still more of an orange shade than yellow. After 30 mins, i washed my hair and AMAZED by the result. It was bright yellow with green undertone! It smells really good. Seeing people’s reaction when seeing my hair is really satisfying! After a few weeks, it’s still as bright as the sun! Thanks, GDY! Wishing for new set of colors!

the colour is STUNNING! i have never ever used a better hair dye. i’ve been dying my hair for over ten years and i’ve used countless dyes. i’ve never been able to get the perfect colour. especially when it came to yellows. i was pretty nervous using the colour because i wasn’t sure how vibrant it would be or how it would look as it started fading. the first day i dyed it i got five compliments! one lady even drove by me in her car while i was waiting at a bus stop and complimented me! even after nine months, the colour was still pretty and i still got many compliments. the dye is very easy on your hair and you get a good size bottle. i absolutely adore hayley and i was excited to try her dye but this blew me away! when ever people ask me about my hair i’m always so proud to gush about good dye young. i’ve gotten several people to try the dye and they all love it! it makes me feel better knowing that i’m using a quality vegan dye without hundreds of harsh damaging chemicals. i will never switch brands. period. the formula, ingredients, pigmentation, packaging, and overall quality of the dye are all game changers. i’m in love with this brand.

I have dark brown hair, which I bleached the life out of very messily. Some strands were WHITE and some were ashy blonde. I applied this product for 45 minutes, rinsed it for 10, and I’ve never been so happy with a hair color.

Ever since GDY came out with this colour I was like “I need yellow hair” and finally, 6 months ago, I bleached my hair and dyed it yellow. GREATEST DECISION. Of all the hair colours I’ve had (a lot), this is my absolute favourite. It’s versatile, bright neon outside, toned down in low light. People on the street compliment me on it constantly, and it looks very cool in black light. It’s also super long-lasting, I’ve only touched it up 2 or 3 times since June. I find a dash of Riot cancels out some of the green undertones and it fades really elegantly to a light brassy blonde look. I’ll be coming back to this dye possibly forever!!!

The neon yellow I have been searching for for a decade! When they say this glows in the blacklight they’re not joking. It turns a blinding electric blue that for sure does not exist outside of a positive luminol test. Y’all. It’s perfect.

I mixed RIOT! and Steal My Sunshine to create a peachy-orange look. Absolutely stunning. GDY’s formula is outstanding and leaves your hair looking better than it was before you dyed it. For best results wash your hair with GDY’s Color Kind Shampoo and condition with the Color Kind Conditioner. The Pre-Wash and Primer also keep your hair healthy and fresh. LOVE YOU GDY.

I’ve dyed my hair A LOT. FOR YEARS. This is the BEST semi-permanent hair dye I’ve ever used. Seriously. Best smell. Enough to cover long and super thick hair. Perfect container that doesn’t make you struggle to get it all out. Most off all, the color is AMAZING. Like holy cow bright neon hair of your dreams amazing! This is everything you’ve ever wanted in hair dye! I get tons of compliments and I’m so happy this exists! Never using a different dye again!!! Wish I could give this more stars!!!

I would rate this product a 10 if the website would let me. I dyed my hair with a different brand 3 years ago and have been scared to alter my hair since. I have really sensitive skin and hair, so I avoid most cosmetic products like that. I was bracing for my scalp to burn terribly before applying my Steal My Sunshine. This dye did not dehydrate/burn/fry my scalp or hair, but it actually helped MOISTURIZE and CONDITION! My hair was rejuvenated after dyeing it!
First impression of this product: The packaging is super detailed and neatly designed. The tube smells amazing, the essential oils blend together to give you a soothing aroma. After using it, I saw that it deeply moisturized my frizzy hair and the color turned out VERY vibrantly! (I went yellow 2 MONTHS AGO and the color is still nearly as bright as the week I dyed it) I also use the GDY Colorcare Wash (shampoo) and Rinse (conditioner) once a week. I recommend this brand to everyone I see with colored hair. I stan Good Dye Young. My girlfriend and I both have Steal My Sunshine in our hair, and we are excited to try the other colors 🙂

This color is awesome. I’ve been getting my hair colored for months to get it to this color and it finally happened. Just a heads up, this color comes out bright orange out of the tube. I had a bit of trust issues so I did two test strands. This rocks. Thanks for the inspiration Josh Dun ??
Hallie from GDY –
Hi!
Our SMS does look very golden yellow in the tube as well as when applied to hair but it does rinse out our signature yellow! We always suggest performing test strands just like you said! Thank you for supporting GDY.

I love this color, first off. Second, it lasted a lot longer than I thought it would (I should say it’s lasting)
I wash my hair in hot water and it’s still lasting through almost a month now!
