First, let me give a 5 star shout out to Cosmetic World for making this product available to non-professionals. I have been shopping here for over 20 years, it is THE best place in Toronto to get products you won't find elsewhere, and great prices as well.
Koleston Perfect 12 series really delivers on the name. It gives PERFECT results!
Eliminates brass!
No need for toner!
Hair stays soft!
Yes it really does get rid of the brass without needing toner, which is a game changer for me.
I use 12-16 with 30 vol developer. Have also tried 12-61 and 12-81 with great results as well.
