Rated 5 out of 5 by from Thumbs up I received this product to test for an honest review. I only got one tube, but I absolutely loved it. I used it for a color melt and it turned out beautifully.

Rated 5 out of 5 by from Absolute best for root melting & gray blending I LOVE L’Oréal dia series. I switched from redken shades and have never looked back. It’s always consistent results even on the most porous, over processed blondies. And no scary processing at the bowl. I do like the new dia color series, I do wish they would bring back 9.02, it was my favorite in richesse for root taps. I lied that you can still mix richesse with dia color. But it’s hands down a staple in the color cabinet, it’s all I use for root melts and for my gray blending.

Rated 5 out of 5 by from New color brand for my color lineup! I’m usually a one color brand girlie! However, thank you to L’Oreal for sending me a sample of their Di Color to try. I will be adding this to my color shelf for sure!! I love the consistency and the beautiful finish!

Rated 4 out of 5 by from This is a nice line of color Consistency is nice and easy to work with. The fragrance isn’t horrible either. I love the shorter processing time and the shine longevity.

Rated 3 out of 5 by from Great Color This was my first time using this color line. I was a little hesitant since it is completely new to me, however it was an okay experience. The final color was beautiful, but I am not fond of the consistency of the color. I felt as though it was very thin and liquid-y. If you don’t have a preference on the consistency of your color, definitely try this line!
Date published: 2025-01-08
Rated 4 out of 5 by from Nice color with little to no odor This line has a nice consistency which makes application easy. I also appreciate that there is little to no odor, if anything a slight floral scent. It did seem to pull a little green and can show a tad darker so I would just formulate knowing that but the color itself leaves hair feeling healthy and shiny.
