Hi I’m also a hairdresser, I booked two and a half weeks off but I would have been fine to go back after a week!! It’s honestly not as bad as you think, my pain was bad for 2/3 days then my arms were pretty useless but I remember thinking just after a week I could have defiantly of gone back!
If you book your own appointments just allow more time as you don’t was to cause any damage also raising your arms really high was still painful so no root lift blow dries lol!! X
