I use shade 5-00. There are no red undertones in this brown like with many other brands, and it leaves my hair feeling healthy and shiny. I use it with the 1.9% developer.

I love the Igora Vibrance series, it provides perfect tone on lightened hair. I started with a shade 8 honey blonde and wanted to make it more ashy; so I ordered 8-11, it provided the correct results, was easy to apply and is very soft on the hair. Development time is only 10-20 minutes as well!

If it is your first time buying beware that you can only use it with a special Igora Vibrance developer that is sold only in big bottles, as it is a professional product. However once you have it you have endless possibilities with the Igora Vibrance series!

Highly recommend as a toning series.

Do not put it on top of decapage, I don't know if you have to mix it with something else for it to hold, but on its own it produces a faded reddish-pinkish-brown on the already opened decapage red.

For those who don't know, in already dyed parts of the hair (lengths), we apply semi-permanent dye to maintain the color that has an acidic pH. The product as a semi-permanent dye is excellent.

It has a very good duration, even though it is semi-permanent. This specific color, 6-12, is very, very cool and quite dark. Never put it on bleached hair because it will turn green after a while (it actually happened to me - it wasn't the product's fault, but the shade I chose). Also, although the instructions state that it should be mixed with the same brand's developer, I used a different brand and had no issues

I tried it on natural blonde hair and I must admit that I was not satisfied. The pink color appeared very faint compared to other semi-permanent dyes I have used, but this "faint" lasted for about 4-5 washes, so in terms of duration, it was okay.

Unfortunately, this product caused a mild allergic reaction for me, with redness and itching on my hand allergy test. Kids, always do an allergy test. I have dyed my hair with various permanent dyes without any issues, but this semi-permanent one bothered me. In terms of color, it didn't do anything on a strand that I applied it to, no change in shade. I had heard good things from internet reviews, but unfortunately, it was a waste of money because it also requires activation from the same line.
