I bought it to do a balayage and restore the copper in my highlights. The issue with red colors is that they fade very easily and require attention. With this specific dye, the color hasn't faded, even though I'm on the 7th wash. With other brands, the color would fade by the 4th wash. I used the 6.44 with a 10-volume developer. In my opinion, it outperforms much more expensive dyes.

Beautiful color and good lasting power, just need to be careful. It easily comes off the skin with a different brand's makeup remover.

I used it with the corresponding developer, there was no itching, only a few seconds when the dye touched the skin. The color is very impressive, a ginger-copper shade. The price is perfect! I will choose it again.. the only thing that bothers me is that it doesn't easily come off the skin compared to another brand I have tried.

Like every dye, it needs the right mixture with the developer and the other shades you will use to achieve the color. It covers the white hair and offers even coverage, but it is quite strong. It causes itching, but I always use it with a different developer. Depending on the brand, it was more intense or not.
It also works better with 30-volume developer rather than 20-volume. In other words, I achieve the color with a 30-volume developer. With a 40-volume developer, it becomes too diluted and over time, the color fades and turns pinkish. I mix it with 9.44. Half and half, so one tube of the color and half a tube of the mixer 0.44. And 90 to 100 ml of developer.
To achieve the desired color.
