A very old thread, but I think it has increased relevance today! I have always gone to Great Clips to get my hair cut because I didn't have the courage to do it myself. Well, now it's the time of COVID, and I don't feel safe getting a haircut, even as restrictions are eased on such establishments.
So, I drug out the clippers I bought on a whim when I was just out of college... I think I used a "3" guard but I'm not quite sure as they're bad clippers and nothing is labeled... A lot of buzzing later, and it looks fine. Next time I think I'll go up a size on top and down a size on the sides and back.
Never paying for a haircut again.
