GDY Hair Lightening Kit

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:

1. Powder Lightener, 1.34 OZ

2. 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:

1. Aloe Vera & Coconut Oil for conditioning and hydration

2. Soy Protein for hair strength and support

3. Castor Oil for optimal softness, shine, and texture

4. Rice Starch for hair that looks and feels smoother

5. Potato Starch to support smooth product application

6. Citric Acid to help balance pH and stabilize the formula

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

Step 1. MixIn 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. TestBefore 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. PrepStart with clean and completely dry hair. Always wear gloves before you begin the application process.

Step 4. ApplySection 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. ProcessAllow hair to process for up to 50 minutes, checking every 5–10 minutes until your desired lift is achieved.

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

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

Step 8. ColorBefore 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.
