  • Lightens the hair and opens the cuticle, to properly receive our ultra vibrant Semi-Permanent pigments
  • 25 Volume Creme Developer, gentle enough for light brown hair but powerful enough to lighten darker hair as well
  • Dust-Free Powder Lightener contains Soy Protein to minimize damage from the lightening process
  • Contains Coconut Oil to help condition the hair
  • Vegan. Cruelty Free. Gluten Free.

  • Lightening your hair will give the most vibrant results from your GDY Semi-Permanent Dye.
  • To create the lightening mix, we’ve made it easy for you! Simply mix one bottle of the Creme Developer with one packet of Powder Lightener in a non-metallic bowl to a creamy consistency.
  • We recommend a strand test before full application
  • 1. Hair should be dry and it’s best if hair is unwashed.
    2. Section your hair and apply the lightening mixture with a gloved hand or brush. (TIPS: saturate the hair and cover it when you finish, to keep the Lightener from drying out. When it dries, it stops working. Protect your skin from irritation by applying shea butter, coconut oil or thick hair conditioner to your hairline and over the ears.)
    3. Let your hair process for no more than 50 minutes, until you achieve the desired tone. Check consistently (every 5-10 minutes) to evaluate the color lift.
    4. After you achieve the desired result, rinse and shampoo your hair thoroughly with warm water until you are sure all of the product is removed. Do NOT condition the hair, as your Semi-Permanent Dye will act like your conditioner when you apply.
    5. Wait at least 24 hours before any further lightening.
    6. Before coloring with GDY Semi-Permanent Dye, make sure hair is totally dry. When it is, you’re ready for color!


  • This depends on whether you are simply doing a small section of your hair or the entire head. An entire head could require 3-5 Hair Lightening Kits depending on length and thickness.
    • To ensure even lift, each hair strand needs to be generously covered in lightener. Saturation is key!
    • The amount of Lightening Kits you will need depends on the length and thickness of your hair. Pixie cuts and mens cuts typically only need 1 box, shoulder length hair typically needs 2-3, medium length hair 3-5, and long hair can be 5+. Remember, it is always better to have more product than not enough!
    • Only want to lighten a small section of your hair? You don’t have to mix the entire Lightening Kit at once. It’s okay to eyeball the powder to developer ratio (1 part powder to 2 parts developer) as long as the consistency isn’t too runny or too thick, it will work just fine. Save the rest for another dye job!
    • When lightening hair, save about an inch of your roots for last. The heat from your scalp causes lightener to work faster and will lift your roots quicker than the rest of your hair. This will ensure even lift.
    • Lightener can dry out, so after it is applied put a processing cap or foil over the hair.
    • Some itching and slight burning is normal, but if the lightener starts to become painful on the scalp you should rinse it out immediately.
    • Do not wash your hair directly before you lighten. The natural oils in your hair help protect your scalp from the lightener.
    • The scalp is more sensitive when it is that time of the month, so save yourself some pain and don’t lighten your hair while on your menstrual cycle.
    • Before applying a semi-permanent dye, you may need to tone your newly lightened hair. If you don’t, the underlying tones in your hair will mix with the semi-permanent color potentially creating an unwanted shade. If your hair lifts more orange, use a blue based (ash) toner. If it lifts yellow, use a purple based toner. This will neutralize the unwanted tones and create a natural blonde base for your semi-permanent color.

      I’ve had my hair bleached and dyed before but always professionally. Since quarantine has kept me inside I decided to color my hair with narwhal and I needed to bleach it beforehand. By far this has been the EASIEST & FASTEST bleaching experience I’ve ever had. My hair is a dark brown and lifted to a nice blonde within 30 minutes and did very very little damage. In all honesty I don’t see any damage at all?? I highly recommend this lightening kit 1000/10

        Hi There!

        I am so so SO glad you loved our lighting kit. Welcome to the quarantine dye club! I’m sure your Narwhal hair looks amazing!

      I’m actually shocked at how light my hair got. I have naturally dark hair so I figured I’d have bright orange hair after my first use, but my roots are blindingly white. Super happy with how this turned out & with how easy it was to use! My only criticism is that I wish there was some sort of graphic to show how much you’ll need- I bought 2 boxes and easily could’ve used another. Overall though I’m super pleased!

      This was my first time dying my hair without my mom’s help at home and thank GOD it’s so forgiving because I fudged up by taking too long so luckily it prevented my hair from falling out! Yike! My unevenness is completely my fault and everything on this products end worked great. One wash with the GDY wash and rinse and my hair was back to normal after my color.

      This is absolutely the BEST lightening kit I have ever used. Typically when I try to bleach the old dyed parts of my hair, they turn out orange while the rest of my hair is the desired blonde color. However this kit did a fairly even job. While the ends of my hair are a slightly darker yellow blonde (which was expected), overall it was pretty even. Will definitely buy again in the future.

      • Jackie from GDY

        Hi Dani!

        So glad you are liking the lift this lighting kit gave you. I hope you are able to create a perfect canvas for your new color.

      The lightening kit is pretty good. You might need a stronger developer if, like me, you have long, dark black hair. It lightens my hair to a bronze, yellow just enough to get my blue/green hair color. It doesnt damage my hair like other lightening products.

      • Jackie from GDY

        Hi Crystal,

        Thanks for your review on our lighting kit. Depending on length, thickness, and color of the hair you may need to lift more than once with our kit. However, I am glad to hear it gave you a great base for the blue/ green color you want and you didn’t experience any damage.

      The Lightening Kit worked amazing! It lifted fairly quickly and effectively while being extremely gentle. My hair felt dry, but not fried or damaged after washing out the product, but the included shampoo and conditioner revitalized my hair- i was amazed! It’s only been three days since using everything and my hair looks great and feels like it hasn’t been touched! Amazing product, excellent results. I would definitely recommend trying it out!

      • Jackie from GDY

        Hi Michael,

      I really liked this lightener. I dyed my hair on my own for the first time and decided on this after a lot of research. I have medium-light reddish hair and it did a great job lightening it to a nice blonde. Hair was a little brittle after washing and drying (before putting on the color), but that’s to be expected. After I put on the color, my hair was in excellent shape! I’m shocked at how beautiful my locks are with bright teal color! This was super easy to use, too. I’d use again in a heartbeat!

      • Jackie from GDY

        Hi There!

        I am so glad to hear you had a great success with our lighting kit. It creates a great base for those bright colors. I’m sure your teal looks AMAZING.

      I never lightened my hair by myself because I see people melting off their own hair and would get scared that it would happen to me. So I bought this to see if I could actually lighten my hair without worrying about measuring stuff. It worked much better than I hoped, tho I didn’t put much on one part out of fear I was going to mess up so it’s a little darker but it worked out and I’m happy with the results.

      • Jackie from GDY

      My hair was medium brown with highlights and I did have to use two lightening kits to get it blonde enough for a good canvas, but even with lightening one after the other, my hair still felt soft and SAFE. There was no fear of my hair breaking off. This stuff is awesome.

      Great product I had black hair and didn’t want to use regular bleach and have previously bought Blue Ruin and loved the product and the condition of my hair afterwards. Only wish it was available in the UK as shipping and customs is quite costly. But the products are all amazing.

      This is hands down the best lightener I have ever used! It worked so fast and lifted my hair to a super light, almost white, blonde—the perfect canvas for vibrant color!! My hair is super thick so I had to supplement with some old bleach for part of my head and the difference in end result was insane. It also didn’t leave my hair brittle or dry like bleach tends to. Now I know to buy two next time. And there will definitely be a next time!!

      This is a great lightening kit at a great price. The product works quickly, and the amount provided was more than enough to cover all of my hair (mine is slightly longer than shoulder length for reference.) I used the kit yesterday, when I washed it out I used the scalp wash to make sure I got it all out of my roots, and after towel drying used the prime spray before blow-drying. I am proud to report that my hair is not damaged and I am not experiencing any breakage, and my hair is fine/thin so I usually expect some damage after a process like this. I will definitely purchase again to maintain my roots in a few weeks. Thank you, GDY!

      This was the first time doing anything to my hair, I have very dark brown (close to black) hair and I expected my hair to be orange once I applied the first time. So I bought two kits so I could do another round and I’m very happy with the results! The smell of the lightener was bearable so that was a plus to my lightening experience!

      Ordered two packs and it perfectly covered all of my hair (just past shoulder length) and lightened my medium brown roots to a nice blonde. It did cause some irritation but I think that’s on my end

        Hi Reece,

        Thanks for your review on our lighting kit. I am so glad you enjoyed it. While we pride ourselves on having a gentle lighting kit, if you do have sensitive skin, much like any other lighting kit, it may cause some irritation.

      This was my first time putting any sort of dye in my virgin black hair, I was really disappointed with the results. It turned my hair so orange and not blonde as I was expecting it. I don’t know what to do because I wanted to dye my hair blue but it will look just so swampy over the orange.

      • Becca from GDY

        Hi there! Thank you for your review. With lightener on black hair, it is possible you may need to lift it twice to get to a nice blonde base. The lightener has to break through all the underlying pigments before the hair reaches blonde and it is possible that it just needs to sit on a bit longer to break through the orange pigments.

      My only regret was not buying more. The kit quickly lightened my medium brown hair and left my hair feeling soft afterwards. Unfortunately, my hair is just past shoulder length and I should have ordered at least two lightening kits the first time.

        Hi Miranda,

        Thank you for your review on our lightening kit! We are glad you love it! Depending on the length and thickness of your hair you may need more than one lightening kit, but that just means you get more fun mail! Happy Dyeing!

      The GDY Lightening Kit worked flawlessly for me! I was able to go from my Dark Brown natural hair to Riot Orange and it looked EXACTLY like the pictures from the models! I am thoroughly in love with GDY and the fact that their lightening kit worked so well for me was just astounding. 5/5 easily.
