Rated 5 out of 5 by from You'll switch to this line, i promise. Just get it, you won't be disappointed. The consistency is perfect- thick but blendable. Every tone is so spot on, there is no mystery with what you're using. After a 10-20 minute toning session the hair is magically smooth and shiny with integrity. Never hollow, dull, or greenish. Great variety of shades. Extremely long lasting toner, especially the coppers.

Rated 4 out of 5 by from Wide variety I like that it balances the PH level after a blonding service. Doesn’t make a mess and have a bad smell like other “toners.”

Rated 5 out of 5 by from New Line Just restocked my Demi’s with the new revised Dia color replacing diarichesse. Looks beautiful, super shiny and easy to formulate. Love the new consistency and more product in the tube.
