I stopped getting expensive hair cuts when my hair stopped growing at an acceptable rate. No one complains, but who would risk that? I’ll either cry or look at you in a very angry fashion. You might not want to choose which you prefer.
Several years ago I invested $20 in a Wahl hair cutting kit and I've been cutting my own hair ever since then. I've saved hundreds of dollars in haircuts.
There hasn't been a single person who has been impolite enough to comment on my haircut. Then again, why would they? It looks the same as when I hired somebody to give me the haircut.
