Oxidizing Emulsion 6% Demira Professional Acti-Vol Cream

I use it before dyeing. I apply it to my gray regrowth. I heat it up with a hairdryer. I rinse it off (because my hair dye also contains an oxidizing agent), dry it, and then dye it. My gray hair is better colored.

I have been using this oxidant for a long time, just like the brand's dye. These products are of very high quality, and the result always turns out very nice. Thank you to the manufacturer!

I constantly use KASSIA Hair Dye, and my hair is in great condition. I am completely satisfied with it. My hair remains in good condition and it hasn't been damaged. It covered 70% of my gray hair perfectly. I highly recommend it.

I have tried this developer myself and I can say that it has the following qualities:
- It does not have a horrible smell.
- It comes in both large and small volumes.
- The price is equal to the quality.
- It has a convenient texture.
- It quickly blends with any paint.

The developer is amazing! I bought it together with this same shade hair dye, shade 7.0. I went from blonde to auburn, my hair looks well-groomed, and it doesn't dry out the ends. The color came out incredible as well. The developer doesn't have a harsh smell, the consistency is nice, and it mixed easily with the dye. I am 100% satisfied with the coloring.

This is my first time purchasing both the dye and the developer from this line. The developer has an unusually thin consistency, but the scent is amazing! The color is evenly distributed throughout the entire length. I have no regrets about choosing to get a whole liter right away.
