I think the best part of this product is the smell firstly, it has the best smell i have ever smelt for a hair dye... its very creamy and easy to apply. I used my free product on my mothers hair as I wanted to test it that way and she was due for a colour. I also used it on my mothers hair as I wanted to see if it actually is 100% grey coverage as the box says and I am not grey yet.. LOL :) Mom has also just a few grey hairs but it did indeed cover it all up. Left the hair silky and smooth and very shiny!!
