For many years I cut my own hair to save money. Then I switched to Supercuts once I felt like I was doing better financially. I like not having to have an appointment, plus they are cheap, have a senior discount, and they do a reasonably good job with my wavy hair.
I had Supercuts give me the shortest haircut of my life last August, right before my knee surgery as part of my preparations for the surgery. This very short layered haircut was so short that it was essentially a "boy cut". It was very helpful to have extremely short hair after surgery since it required zero care while I was in the hospital and recovering. It took until maybe February to grow out.
Now it's getting a bit long and shaggy. But I am NOT going to cut it myself! That's a lot of work and takes me forever to do. Instead I am reverting to my 1960's "long haired hippie girl" appearance, and if that starts looking worse than it does now, then I can always tie it in a pony tail or something until I can go to Supercuts once again.
