I’ve used Colour 7.31 on my grey hair and it covers perfectly. The color is bright and even, and my hair feels smoother after application. No damage or dryness, which is a big plus.

The shade is true to what I expected. It gently lifts my hair by 3 levels and still looks natural. I love the argan oil in it—it makes my hair feel softer.

Great coverage for grey hair. The color stays vibrant for weeks. A bit more expensive, but the quality and results justify the price.

I tried several permanent dyes before finding this one. The low alkaline formula is kind to my hair. It’s not too harsh and keeps my hair healthy.
