Wissenswertes zu Developer & Preparation

Developers and oxidizing agents for coloration, bleaching, and toning: Here you will find developers from 1.5% (5 vol.) to 12% (40 vol.), including brands such as Wella (Welloxon Perfect), KYO (Bio-Activator), Black Professional, Parisienne, and Freelimix, in sizes ranging from 150 ml to 5 liters. We also offer preparation accessories: wipes for removing color stains, a silicone highlighting cap, a coloring apron, and a toning activator. Always choose a developer that matches your color system and the desired level of lift. You can find colors under hair color and bleaching powder under bleaching.

Which developer strength do I need for what?

As a guideline, Wella recommends the following for Koleston Perfect: 6% for gray coverage and the same depth of color or one tone lighter, 9% for two levels of lift, and 12% for three levels of lift. Lower strengths such as 1.5% or 3% are primarily used for toning and treatments that do not require lightening. The instructions provided by the respective color manufacturer are always binding.

What does "vol." mean on developer products?

Vol. stands for volume and describes how much oxygen a developer can release. These values correspond to fixed percentage values of hydrogen peroxide: 5 vol. is 1.5%, 10 vol. is 3%, 20 vol. is 6%, 30 vol. is 9%, and 40 vol. is 12%. For many products, you will find both specifications directly in the variant selection.

Can I combine developers from different brands?

Manufacturers recommend mixing their colors with their own specific developers. For example, KYO points out that using a different oxidizing agent or altering the mixing ratio can impair the result. For reliable and repeatable results, it is best to stick to the color manufacturer's system and test any new combinations on a sample strand first.

How should I store developer correctly?

Store developer tightly closed, in a cool, dark place, and keep it out of the reach of children. Do not transfer it into other containers and only mix the amount you need immediately—mixed color or bleach should not be stored. Further instructions can be found on the label.
