Mixing hydrogen peroxide cream (developer) with hair dye cream is a crucial step in the hair coloring process, as the developer activates the color molecules in the dye, allowing them to penetrate the hair shaft and create the desired color. Here's a step-by-step guide on how to mix hydrogen peroxide cream and hair dye cream:

1. Gather supplies:

Ensure you have the following items:

• Hair dye kit containing the hair dye cream and the corresponding hydrogen peroxide cream (developer)
• A non-metallic mixing bowl (plastic or glass)
• A tinting brush or applicator bottle (if not included in the kit)
• Gloves (usually included in the kit)
• A timer

2. Read the instructions:

Carefully read the instructions provided with your hair dye kit. Pay close attention to the recommended mixing ratios, processing times, and any specific application instructions for your chosen hair color and developer strength.

3. Put on gloves:

Protect your hands by wearing the gloves provided in the hair dye kit.

4. Measure and mix the hair dye and developer:

a. Check the mixing ratio: Refer to the instructions to determine the correct ratio of hair dye cream to hydrogen peroxide cream. Common ratios include 1:1, 1:1.5, or 1:2 (dye:developer), but always follow the specific instructions for your product.

b. Pour the developer into the mixing bowl: Using a measuring cup or the markings on the developer bottle, pour the appropriate amount of hydrogen peroxide cream into the non-metallic mixing bowl.

c. Add the hair dye cream: Add the corresponding amount of hair dye cream to the bowl, following the recommended ratio.

d. Mix thoroughly: Using a tinting brush or spatula, blend the hair dye and developer together until the mixture is smooth, uniform, and free of any lumps. Be sure to scrape the sides and bottom of the bowl to ensure all ingredients are well combined.

5. Timing is crucial:

Once the hair dye and developer are mixed, the clock starts ticking. The mixture should be applied to your hair immediately, as the developer begins activating the color upon contact. Set a timer according to the recommended processing time specified in the instructions.

6. Apply the mixture to your hair:

Follow the application instructions provided with your hair dye kit, typically involving sectioning your hair, applying the mixture from roots to ends, and ensuring even coverage. Start with the roots if you're touching up your roots or applying an all-over color, and work through the lengths and ends if you're doing a root touch-up.

7. Process the color:

Allow the color to develop on your hair for the recommended processing time, checking the color periodically (every 5-10 minutes) to monitor the progress and avoid overprocessing. When the processing time is up, rinse your hair thoroughly with cool or lukewarm water until the water runs clear.

Remember to always follow the specific instructions provided with your hair dye kit, as mixing ratios and application methods can vary between brands and products. Mixing hydrogen peroxide cream and hair dye cream correctly is essential for achieving the desired color results and maintaining the health of your hair during the coloring process.
