Remington trimmer with a 2.5mm comb attachment, five minutes going over once a week. It’s what I do. I used to get the barber down the road to do it, £10 once a month until lockdown, when I faced up to the inevitable and just took the lot off with my beard trimmer. It wasn’t that long, but it was such a waste of time and particularly money trying to keep what little I had in some sort of style. I’m 68, and realised I ought to have done it a long time ago.
