For me, it depends on my lifestyle. I am very dark but going grey. I tan easily and have brown eyes. If I dye my hair it's original colour, I look like I'm wearing a wig, as my skin tone has changed, unless it's summer, when I can get away with it. When I had a full time, senior job, I dyed my hair regularly. Since I started working for myself a couple of months ago, I stopped. I kind of like it. No one has commented. I may go back to colouring it again but for a while at least, I'll stay a mix. I'm a middle aged tomboy at heart!
