I have taken mine just ask hairdresser if it's OK shouldn't be an issue though
I bring my baby to the hairdressers for a blowdry every week😂 they don’t mind!
I would ask the hairdresser first. I’m lucky in that mine said yes, and there was no issue, but best to ask. Go prepared with plenty of things to keep them stimulated though.
My SIL let the hairdresser know beforehand and they made it very comfortable for her in advance ☺️
