Over 10 years here and never visited a hairdressers/barbers. A long time ago during my prog rock period, (well 1974 actually) I had long hair and a full beard. (I still have a copy passport photo from then to remind me what hair looked like). The hair I have left gets trimmed myself. A baseball cap or wooly hat keeps the grey matter warm normally. When that very cold spell hit us, I went unshaven for a while and decided to keep the resulting growth in moustache and goatee form. It may last till I visit my Mum around August, it doesn't match my present passport photo (does anyone look like their's?) and she'll hate it.
BTW, returning to the topic LOL, it's a beautiful cloudless day here, which is making me feel guilty about re lighting the Rayburn. But then I look at the forecast and gain a modicum of reassurance that I made the right decision.
