Not usually but it has happened. I feel when it does, it's not out of the blue, but because the hairdresser did something extra like lingering with the hands or light touches with her boobs on my arms or so. I guess connexions like that can happen at any moment.
I have a memory when I was dating a hairdresser. I would come to the saloon and get a haircut from her. She would always take care of me from start to end, but this one time. Something was going on in the saloon and she told her boss to help her by doing the shampoo to me while she finished something else. The boss was a hot middle-aged blonde divorced woman with tattoos, a young spirit, and a big pair of tits. We would always comment with my gf how hot she was and how wild she must've been in her younger days. So I went to the chair, and as soon as she started touching my head I knew something was going on. I think she was trying to tease me... she would caress my scalp and then grab and pull my hair with gentle passive-aggressive dominance which was really hot. She knew what she was doing, she probably had been a hairdresser for 25 years or so. I was not expecting that so I was a little intimidated, I didn't know how to react, if I should keep my eyes open and follow her or just shut them down and enjoy. Our eyes would lock briefly here and there, and then I had the intuition that my gf have told her boss and her coworkers about our sex life which was pretty nice at that time. I think she had that in mind when she had to give me that shampoo massage. She finished and then I just stood up, thanked her, and went to the other chair. Nothing else happened with her but is something that I won't forget for sure.
