I'm 42 and almost completely grey - not that you would know it thanks to my wonderful salon touching my roots up every 4 weeks. My hair is in terrible condition thanks to the frequent colour and the heat from hair dryer/straighteners. I'm also worried about developing allergies as my hair is so dark. I've started to think about the future and don't want to be a pale faced 80yo with black hair. I feel to young to see a grey haired lady looking back at me in the mirror, but I resent the time and money spent on topping it up every few weeks. What are your thoughts on colouring and going grey and what do you do to hide the inevitable?
