This kind of nonsense is the reason I've not been to a hairdresser since I was 16. Which is both a) a very long time ago and b) readily apparent just by looking at me.
Since the pandemic, I've been growing my hair out then shaving it off every few months. After going to the hairdressers once since then, I remembered how much I hate it. Been cutting/shaving my own hair ever since.
And it feels good to time the shave when I have a period of stress and frustration. Going through the process is like a rebirth and helps me mentally reset.
