I am having to colour my hair every 4 weeks to cover the grey roots coming through and was wandering what others do re:this covering of grey problem. Had to start doing my own hair last year to save money, I hate doing it anyway, but the thought of doing this every month for years to come depresses me. My natural colour is dark brown/auburn and I am trying to keep to this colour (tatty recommended nice and easy 117 - lovely colour), maybe I should think about going lighter so greys wont be as obvious? Any ideas?
