.... So on for just over 10hrs and my greys still aren't completely covered
Its better coverage than when I only left it on for 2.5/3hrs but I was expecting no signs of greys at all. What am I doing wrong? I applied it with one of those hair dye paintbrush things, kept it over the heat so it hadn't cooled at all when I applied it and then wrapped it in cling film straight away. I'm not impressed!
