Following a period of illness, I've been unable to get to the hairdresser to get my colour done. I'm now half grey / half brunette. Not sure how I feel about it. On the one hand, I've got more important things than my hair to worry about and I am well on the way to growing out the colour. On the other, my illness has made me feel sad and old and when I look in the mirror, I see a sad, old version of me. Should I leave my hair and power through to full greyness, or get it coloured?
