Sapphire Collagen Oxidizing Cream 30,9% Inebrya Bionic Activator Oxycream 30 Vol 9%

The 9% hydrogen peroxide cream works well with the lightening powder of the same brand. However, the emulsion dries out prematurely. It is best to mix it with the cream halfway when dyeing thin hair. For porous hair, the cream is a better option.

Great developer! I use it with Garnier hair dye 10.21 and it works perfectly! It doesn't damage my hair, leaving it smooth and silky.

Great, I use it with paint from this manufacturer.

I received a mini-sized product as a gift for participating in a promotion, and I decided to purchase the larger bottle. This oxidizer is excellent and efficient, with a pleasant fragrance, and the name is beautiful too!

One of the best developers I have tried. When lightening by several shades, it doesn't make the hair look like straw, they remain smooth and shiny, and the typical yellow shade of "over-bleached" blonde does not appear.
