Sapphire Collagen Oxidizing Cream 20,6% Inebrya Bionic Activator Oxycream 20 Vol 6%

I ordered hydrogen peroxide, and I am satisfied with its quality. I highly recommend it.

Oxidation is good, but it seems like the manufacturer may have changed the composition because it slightly differs from what is indicated on the website, although not significantly. It is very thick, so if you don't like that, it's better not to get it.

I am completely satisfied with this hair bleach cream.

My favorite developer, it doesn't over-process the hair, and when combined with hair dye, it creates a beautiful shade of blonde. Just one jar of this is enough for all of my hair, which is slightly shorter than shoulder length.

Unfortunately, after using this developer for dyeing, I noticed that the water became dark every time I washed my hair (I dyed it with a dark chestnut shade). This was my first time using this developer, and I will not be using it again. I have never experienced this issue with other developers.

Excellent product, I bought it to lighten my roots with a 1:2 powder ratio. The result is fantastic, my hair looks amazing. The mixture of cream and powder creates a thick consistency (thicker than the developer), but the outcome is excellent. I am pleased with it!
