I was not impressed with L'Oreal Mousse Absolu. I have thick curly hair that's a little below shoulder length and I barely had enough product to do a full application let alone have leftover for touch ups. There was very noticeable alcohol smell because of the mousse can. Also I found it very time consuming and messy. Time consuming because I had to shake vigorously before spraying each time and then still had to massage it in. Messy because when I applied it to the back of my head a foam ball fell on my bathroom rug and I had to wash it afterward. Finally, I'm not sure how good this would be as a root touch up because it does not offer precision application like a traditional home color which can be applied with a brush. The only good thing was the color results were nice, but I think I'll stick with the traditional home hair colors.
