I started that like 10 years ago, unfortunately I have a funky shaped head so it doesn’t look as good as it may on others but I do enjoy the maintenance on it. I can definitely tell these days it won’t grow back like it used to (much thinner on the top, edging back on the top sides). However being able to use a hair trimmer once a week myself is cheap, and less things to do while getting ready in the morning.
I can understand since society seems to put value on hair but not worrying about it (some confidence) goes a long way. I barely think about it nowadays.
