A few years ago I was able to get L'Oreal Grey Chic, but have been unable to buy it locally for some time.
I found it very easy to use and was always satisfied with the colour produced. At that time there were three different shades of "Chic" grey, and I tried them all. For my hair I preferred the silver one.
I was very disappointed when I could no longer obtain it.
I still have some of the bottles; very handy on holiday, and I also kept the spectacles' cover.
