Complete Your Routine

The Facts

We did the work for you! The GDY Hair Lightening Kit includes everything you need to prep your hair and create the perfect canvas for applying vibrant semi-permanent hair color.

Every single-use kit comes with pre-measured components in a convenient 1:1 ratio:

Powder Lightener, 1.34 OZ
Crème Developer, 4 FL OZ

This formula gently, easily, and safely lifts hair 4-5 levels. It contains a 25 volume developer that is powerful enough to lift the hair while being safe for at-home lightening.

During the lightening process, moisture loss is replenished with conditioning ingredients that help keep hair feeling soft, strong, and nourished.

Infused with hair-healthy ingredients:

Aloe Vera & Coconut Oil for conditioning and hydration
Soy Protein for hair strength and support
Castor Oil for optimal softness, shine, and texture
Rice Starch for hair that looks and feels smoother
Potato Starch to support smooth product application
Citric Acid to help balance pH and stabilize the formula

This formula is 100% vegan, cruelty-free, and gluten-free.

How To Use Pro Tips Ingredients

Step 1. Mix
In a plastic bowl, mix the pre-measured Powder and Developer until smooth and fully blended. Use only the components included in this single-use kit. Do not mix with other lightening products or mix multiple kits in the same bowl at once.

Step 2. Test
Before full application, it is essential to perform a strand test on hair and to complete a patch test on skin if applying to the scalp.

For a strand test, apply a small amount of lightener to a section of hair on the back/underneath and process for 30–50 minutes. Rinse and assess the condition of the hair. If it feels overly stretchy or cotton-like, do not proceed.

For a patch test, apply a small amount to the inside of your forearm and process for 30–50 minutes. If irritation occurs, avoid scalp application.

Step 3. Prep
Start with clean and completely dry hair. Always wear gloves before you begin the application process.

Step 4. Apply
Section hair into four parts by dividing down the middle and across from crown to ear. Using your hands or a brush, begin applying the GDY Lightening Kit to the bottom and middle sections first, starting about 1 inch away from the roots. Fully saturate each section working up the head.

Pro Tip: Heat from the scalp causes lightener to process faster. Apply to the roots last, once the rest of the hair is about two levels away from your desired color to help avoid hot roots. Fully saturate the hair and cover with it plastic wrap to keep the lightener from drying out. Protect your hairline and ears with shea butter, coconut oil, or thick conditioner.

Step 5. Process
Allow hair to process for up to 50 minutes, checking every 5–10 minutes until your desired lift is achieved.

Step 6. Rinse
Rinse thoroughly with warm water, then shampoo and condition until all product is removed.

Step 7. Wait
If your hair has not reached your desired level of lightness after 50 minutes, wait at least 24 hours before lightening again.

Step 8. Color
Before applying GDY Semi-Permanent Hair Color, ensure hair is completely dry. Then, you’re ready for color!

When lightening hair, always 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 an even lift.
To optimize performance and safety, do not mix the GDY Lightening Kit with other lightening products or kits. If using more than one kit, mix each in a separate bowl. Do not store or reuse once mixed.
Only want to lighten a small section of your hair? Our Streaks & Strands Lightening Kit is perfect for money pieces, buzzcuts, bangs, dip-dyes, and everything in between.
Before applying a cool-toned 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 result. 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. Try our Platinum DYEposit as a toner!
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.

Reviews

All in this together burgundy

"Very vibrant color! It looks so amazing and very pigmented. I love how nice and soft my hair feels after using it"

— Valeria Z. (5/5)

First time!

"I used this lighting kit for the first time on my virgin black hair and although the smell was a little strange, it lightened my hair without damaging it at all which is something that I hoped for, it kept all of my coils in tact and didn’t damage anything! I only saw a few videos of people with my hair type using this so that’s all I had to go off of and I’m soo super happy that I trusted my gut!"

— Allyssa (5/5)

Best lightening kit!

"This is the only brand I buy now. I never get any kind of chemical burn after using it and it works so well to lighten hair. It makes any of the colors you buy pop so well."

— Kiara N. (5/5)

works great

"this kit is gentle yet extremely effective at lightening your hair several levels. my natural hair is a level 7 and this kit can get it up to a 10 within 20 minutes from application. i really appreciate the convenience of premeasured bleach and developer so my application always has consistent results."

— Rachel (5/5)

Kowabunga

"My favorite green to dye my hair!! Such a good jewel tone!"

— Griffin J. (5/5)

Best boxed lightener kit

"I always used to dread lightening my hair at home, but this kit has made it a lot less worrying! I do appreciate that everything is already measured, and haven't noticed any damage anytime I'm touching up my hair. It's also gotten me gorgeous lifts!"

— Tayler (5/5)

Slay

"Lightens fast and well none of my hair fell out"

— Rowan C. (5/5)

Lifted My Color So Well Without Damage

"This hair lightening kit worked surprisingly well! It lifted my color evenly and left my hair feeling soft instead of dry or brittle. The results were clean and consistent, making it the perfect base for applying vibrant dye afterward. Really impressed with how gentle yet effective it was."

— Autumn (5/5)

The only kit I’ll use

"It will lighten my medium-dark hair to somewhere in between a 9 or 10. My hair doesn’t dry out or stick together (an issue I had with a different brand), and leaves my hair smooth and smelling good. The only downside is the amount of product I need and how much money I sink into it, but last time I went with a cheaper brand/product I wanted to rip my hair out from being so dry and sticky."

— Molly (5/5)

Get it now

"This bleach saved my hair! I bleached my hair for the first time with this kit and it didn’t damaged my hair at all! My hair actually feels softer and healthier when I bleach it. I went to the beach and the sun lightened some of my hair, I ended up bleaching some of my hair that was dry front the sun bleaching it and it was softer after the bleach! Definitely recommend."

— Myla B. (5/5)

Q&A

How does this compare with traditional bleaching products? Is it pretty dummy proof? I am the dummy lol. Or do I need to be able apply it with as much skill as I would typical bleach? Also, I have about an inch or two of grow out from my scalp to bleached hair (I'm naturally light blonde). Would it be risky to use this kit, as it may create a banding effect? Thank you!: Hi Kat, Our Lightening Kit is formulated with 25 Volume Creme Developer so that your hair is left in good condition while offering just the right amount of lift to achieve lighter results and create the perfect base for our semi-permanent hair dye. While our developer is a lower volume from what you may have used before, this lightening kit still features a bleach and developer. You can use the GDY Lightening Kit on your regrowth, but we strongly advise you do not overlap onto previous lightened hair as this can cause breakage. With 1"-2" of regrowth, slight banding is to be expected. The immediate root will be a little lighter than the area lower than that between the first half inch and previous lightener. You can use Platinum DYEposit to help even out your tone prior to applying hair dye. If you have any further questions, email us at help@gooddyeyoung.com.
