Explained to the lady that our son is on the spectrum and has lots of energy. She completely didn't bat an eyelid made the experience actually very enjoyable for us as a family even though we were dreading it. The haircut was shorter than we would of liked but not the hairdressers fault, we had used previous barbers who had given a bad haircut and so it had to be short to rectify which was communicated and understood.
Thank you again! Give this hairdresser a payrise if you can she was fab!!
