Have had good haircuts in the past. One time mentioned something about a "4" attachment ??? Then, next time thinned hair first. Both were good. But yesterday, hair was about 3 inches long, and after saying I wanted hair cut back enough to comb without it curling, I noticed a lot of hair coming off. Deborah used a "2" attachment and basically shaved my head. After the first 3 seconds, it was obvious that it was extremely short where she had cut. She asked if that was a little short but what can you say at that point. Took her all of 5 minutes to finish. I have almost no hair (just a few strands) on the top. She asked if I wanted them cut. I said yes, all they do is stick up. Not enough to even see. She clipped with scissors for about a minute but when I got home, it looks like none were cut. My wife is going to have to cut them back. Looks like I tried a comb-over with 10 strands of hair. At the end, Deborah mentioned maybe I need to ask for a 3 next time. Not sure what a 2, 3, or 4 does or means but worst hair cut ever.
