I have been a Framesi 2001 hair color product user for 13 years. I have worked with other color products, 4 to be exact and have always come back to Framesi. Its ultra-high quality, and predictability have earned my trust over the years. When used correctly the color is precise, and the integrity of the hair remains intact.
If you are looking for high quality hair care professionals, seek out those who use Framesi as their color line.
