Oh boy.
I am 40. I started colouring my hair at the salon but can no longer afford that indulgence. I've learnt that I need to use the colours without any reds/coppers in them because after a couple of months my hair looks too reddish.
I also don't like to go too dark which is a mistake a lot of women make I think.
So, not too dark, not too red.....= chocolate brown. Actually I think the actual colour I use is described as Mocha.
It might not be great, but I certainly feel better than having loads of grey.
