Been cutting my own hair since the 90's, its so simple to do, and saves me time and $$. In the early years of doing it, I made some really bad mistakes, grooves when I forgot I didnt have a guard on. But now I think I can cut my hair better than I get it cut at a salon, and for $35 cheaper.
Working from home for the past 2 months, I decided to try cutting it differently, if I screwed it up no one would see it. I watched some youtube vids, and well, it actually turned out really good, and I kinda wish I changed it up years ago.
Nows the time to try doing it yourself, assuming you are not working publicly at the moment.
