Won't do Grey

I got this in the brunette shade just for my roots in between colouring my hair. I have 10% straggly greys and those are what show up most in my root line... but this mousse dye doesn't dye those so it's completely useless for me. I leave dyes in longer than recommended (40-50 mins) and still it didn't touch the grey. We're not all teenagers dying our hair just to change the colour, I only do it to hide the greys. It's too bad b/c I loved this formula; the white foam dispenses easily and it's easy and mess free to massage into scalp. LOVE that I can use any size amount and still have the rest of the can so if I was just doing root line and around the face this would last a long time. Too bad it doesn't cover the grey, b/c it colour-matched perfectly too

I would not buy this product again.

1st time use of preference mousse #600 to cover my grey roots, to my disappointment this product did not cover my grey roots at all, would not recommend.
