مستحلب مؤكسد jNOWA Professional OXY 3 % (10 vol)

The 3% hydrogen peroxide with this brand's powder gently lightened my hair. I highly recommend it!

This developer is extremely aggressive, especially when used at 3%. It turned my soft hair into a mess, and even the Sienna oil in the dye couldn't help.

I am constantly dyeing my hair with Sienna hair dye and jNowa oxidizer, and I am very satisfied with the result of the coloring. I have very few gray hairs, so it dyes beautifully with this percentage of oxidizer.

Oksydyn is great, it interacts well with the paint. I highly recommend it - the price and quality of the product are superb.

The oxygen is good and interacts well with the paint. I recommend it to everyone - the price and product quality are superb.

I have been using this product for a while now. I dye my hair very often using this developer. I highly recommend it! It has a pleasant price and comes in a large size.

Very good developer, I have been using it for a long time, just like the paint from this brand. The product is of high quality and has a pleasant scent. I highly recommend it. It is easy to use and I haven't encountered any issues. The delivery was fast, thank you.

The product is of high quality. I use it with the paint from the same brand. I am very satisfied with the developer - it doesn't sting and has a normal smell, almost unnoticeable. It performed its job well. I bought it for the dark brown Siena 3/7 hair dye, and everything turned out great.
