Why not? If you're fine with a simple haircut, it's really quite practical. I'm a guy and do a simple taper fade from 1" on top to 1/4" on bottom (similar to this).
My brother did it for years and he got to a VP level role at a large insurance company. If he did a bad job, there's no way he would've gotten that kind of role because it's as much about personal presentation as it is about competency.
I have my wife check it each time, but I don't have her do it because I think I do a better job.
