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

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

This is something I've never seen before. It hardly glows and lasts only an hour. I have been using this bleach for 15 years, and the powder always washes off in 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 after dilution and after 5 minutes). I thought it was supposed to be like that. 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 became softer). I dyed gray hair with a dye from a different manufacturer, so maybe that's the problem. However, I have done the same thing 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 part and then 9% on the top part of the hair. It lightened perfectly, surprisingly. And the hair is much better than after using 12%.
After lightening, toning is necessary! Amazing result and great savings if you do it at home instead of going to a salon. But of course, this is assuming you know how to do it.
Makeup is always on point, I love this service.
