Rated 5 out of 5 by from Works great I love the creamy texture of this toner. It leave hair feeling more soft over a gel toner. Smell isn’t too bad as well, kind of sweet. I would use again.

Rated 5 out of 5 by from Skincare for your Hair I have always loved Dia Light, but adding hyaluronic acid changes the game! It's like skincare for your hair, and makes even the worst hair feel soft and shiny. It comes in all of the best tones for perfect toning on blondes especially.

Rated 4 out of 5 by from Great reformulation Love the new formula and bigger amount of color. The finish has better fuller coverage while still maintaining the shine. Not loving the new packaging, because DiaLight, DiaColor, and Majrel are all very similar looking and easy to mix up in my locker.

Rated 5 out of 5 by from Great for toning I love how soft and shiny it left the hair after using it as a toner. The color has a nice consistency and smell, and left the color nice and even, and didn’t grab immediately or go too dark, like other toners I’ve used in the past. Overall they applied beautifully, results were great and I will be trying other shades as well.

Rated 5 out of 5 by from Great consistency I love the consistency of these demi colors. And i love the fact that it’s a 1/1.5 mixing ratio which means you get more color from one tube. I used these to tone and got pretty great results. Would definitely try them again.
