I'd have thought hair salons would be shut.I’ve used a wahl for years too. I’m lazy so usually go for a grade 2 and will cut it after about 3 months when’s it pretty long. Currently rocking a 0.5 on its shortest setting.
There’s a good place for about £5 up the road that I sometimes go to, but usually I can’t be bothered to wait and do it myself.
