Developer and Peroxide FAQ

What is hair color developer and why is it needed?

Developer (hydrogen peroxide) activates hair color by opening the cuticle and enabling pigment to enter the hair shaft. It comes in different volumes (10, 20, 30, 40) that determine how much the cuticle opens and how many levels of lift you achieve.

What is the difference between 10, 20, 30, and 40 volume developer?

10 volume (3% peroxide) provides deposit only with no lift. 20 volume (6%) gives 1-2 levels of lift and is the standard for grey coverage. 30 volume (9%) provides 2-3 levels of lift. 40 volume (12%) gives 3-4 levels of lift and is used for high-lift shades only.

Can I use any brand of developer with any hair color?

It is best to use the same brand developer and color together. Brands formulate their developer and color to work as a system. Mixing brands can result in inconsistent results, incorrect consistency, or unpredictable processing. Some brands have proprietary developer formulas that differ from standard volumes.

How much developer do I mix with hair color?

Standard mixing ratios are 1:1 for most permanent colors, 1:1.5 for some demi-permanent lines, and 1:2 for most powder lighteners. Always check the brand-specific instructions. Measuring by weight (using a scale) is more accurate than measuring by volume.

Does developer expire?

Yes. Most developers have a shelf life of 3 years unopened. Once opened, use within 12 months. Expired developer loses potency, meaning it will not provide the expected lift or processing. Store in a cool, dry place away from direct sunlight. If the consistency changes or it smells off, discard it.
