Nourishing Creamy Developer for Blonde Hair 6% L'Oreal Professionnel Blond Studio Creamy Nutri-Developer Vol.20

I have no complaints about this product, as I have been using it for a long time with the L'Oreal Platinum paste.

I have never experienced anything like this before. It practically didn't fade, it lasted for an hour. I have been using this bleach for 15 years, and the powder always rinsed off within 20 minutes.

I bought a 9% solution and mixed it with the dye, but there was no reaction (the color of the mixture remained white both during and after 5 minutes). I thought that was how it should be. However, when I applied it to my hair, there was still no result. I thought maybe I didn't leave it on long enough, but when I repeated the procedure and increased the coloring time, the effect was still zero (although my hair did become softer). I dyed my gray hair, but the dye was not from the same manufacturer. Perhaps that's the problem, but I have done this before with other developers and never had any issues.

Excellent developer. Previously, I used 12% for lightening with ammonia-free paste. I decided to try 6% on the back of my head and then 9% on the crown of my hair. It lightened surprisingly well. And the hair is much better than after using 12%.
After lightening, toning is necessary! Amazing results and great savings if you do it at home instead of a salon. But of course, this is assuming that you know how to do it.
Makeup is always on point, I love this service.
