I'd always had long-ish (for a man) and groomed hair until I was 22 when in a fit of depression and frustration I shaved my head completely and it's now my go-to move whenever I'm feeling a bit defeated and opressed by everyday life. I would recommend it to anyone, it will always grow back. But I tried to cut my boyfriend's hair after 18 months of not getting his trimmed (lockdown and a broken leg before that) and it was a disaster, he looked like he was in remission following a near-death treatment.
