When mixing hair color, what is the general ratio of developer to color?

The general ratio of developer to hair color is typically 1:1 or 1:2, depending on the specific product being used. This means for every one part of hair color, you would mix it with an equal part or double the amount of developer. The choice of ratio affects the final result; a 1:1 ratio often provides more intense color, while a 1:2 ratio can result in a lighter, more translucent effect.

Different manufacturers may have specific recommendations based on their formulations, which is why it's important to check the product instructions for the exact mixing ratios. This flexibility in mixing is crucial for achieving various outcomes in hair coloring processes, such as changing the intensity of color or adjusting for different application techniques.
