I'm 53 and my dark brown hair is just starting to go grey at the temples. My hairdresser says that in these early stages she can match my colour and paint dye just on the grey hairs, but as it spreads I'd eventually need to decide whether to grow that out and embrace the grey or dye the whole head of hair. I've never dyed my hair before, so need to decide whether the ongoing maintenance is worth the hassle. If you've gone down the strategic hair-painting route at a similar age, how much time did it buy you before you had to go for a whole-head decision and, whatever you decided, what have been the pros and cons?
