Gordon MacDonald –
I’ve used several hair color products before, but Koleston Perfect gives the most natural-looking result. The color is balanced and doesn’t look too bright. My grey hair is fully covered without any harshness. The application was easy with the 1:1 ratio. I did the allergy test as advised and had no issues.
Diana Vaughan –
The coverage is excellent, especially on my mixed grey hair. The shine is natural and the color stays vibrant. I noticed less product buildup compared to other brands. I still recommend doing the allergy test before first use.
Boris Dowd –
I tried this after having a bad reaction to a previous product. The ME+ technology seems to work well. My hair looks healthy and the color is even. No irritation during application. The lift is just what I needed for a more vibrant look.
Joanne Ince –
The color is good, but I found it slightly less vibrant than expected. The coverage is solid, but I had to apply a second coat. The instructions were clear, but the product didn’t match the sample I saw online.
