The last haircut I paid for was in 1983, when a "stylist" cut my ear and did not mention that it had bled down onto my nice new dress shirt. She had a fit when I did not tip her but I considered the fact that I did not ask her to pay for my shirt to be her tip. I took a year off from college shortly after that and worked two full time jobs that did not involve any people contact so I didn't bother with my hair. When I returned to college, my hair was in a ponytail and I cut it myself by just pulling it down and cutting the end off. Over time, I got better at cutting it shorter with a scissors and comb and I have been cutting my own hair ever since.

I cut my wife's hair too! I was terrified of doing it but I just watched her get a few $75 cuts and paid close attention to how they did it. Eventually, I found that I could replicate what they did and since I was doing it more often, her hair is in better shape because of it.
