1-Liter Size: The 1L (1000ml) bottle offers a larger volume, making it ideal for frequent use or for salons and professional applications, providing excellent value.

Smooth Texture: The cream developer has a smooth, easy-to-apply texture, making it simple to mix with color products for a consistent mixture that applies evenly to the hair.

How to Use:

Mixing: For most permanent color products, mix the Wella Developer Volume 20 in a 1:1 or 1:1.5 ratio with the desired Wella hair color or toner. Follow the instructions on the color product to ensure correct mixing proportions.

Application: Apply the mixture to clean, dry hair, starting at the roots and working your way to the tips. Make sure the hair is fully saturated for even color coverage.

Processing: Allow the color to process for the recommended amount of time, typically 30-40 minutes, depending on the desired result and the specific color product you’re using.

Rinse: Once the processing time is complete, rinse the hair thoroughly with lukewarm water until the water runs clear. Follow up with a color-safe conditioner.
