One near here, in a shopping centre charges £4.99 - which is where I go for the No6 up the back and sides, with the scissors on the top. Usually once per month, determined by my eyebrows being over long and needing a trim. They do it by poking a comb through and trimming what protrudes. I was almost due when we went into lockdown.. They annoying me when they get too long and in my vision.
I've pestered partner to have a go but she point black refused, despite having a clipper kit and a shaver with a trimming head both with the guides. Nowt else for it so I set the shaver on No 6 and ran that over my eyebrows. They look fine and it was so easy, but I would not dare tackle my barnet.
