I've had variations on a bob my whole life (my hair is fine and looks straggly past my shoulders). I never enjoyed going to the hairdressers but never considered cutting my own hair (except for when I had a fringe and it needed a trim).
Covid gave me the chance to learn how to do it myself and I've never gone back. I invested in a good pair of scissors and some thinning shears.
I just cut the length to where I want it, add some layers, thin out the underneath and it's done.
If you do your own, what style do you go for? Do you think you'll ever go back to paying again? I really don't think I ever will.
