I used to be a hairdresser and still do it outside my job now, I did hair 2wpo and was absolutely fine and had no problems at all. The only thing I’d say is that I did struggle to lift my arms up high for over a week and lost a bit of strength in them, but if you have the seat at the right height so you’re not stretching too much you shouldn’t be too bad. I had overs though and I know the recovery time with unders can be a bit longer xx
