My husband has straight hair he keeps in a tight fade, like nearly bald on the sides to very short at the top, and gets his hair cut every 2 weeks. I (lady, curly hair) can go a year between, just get it cut in short layers and let them grow out to long layers. The two of my kids who like theirs short but not crazy short go a month or two between.

Basically the shorter it is, the more you have to cut it - hair grows, on average 1/2 inch (13mm) per month, so mine has a 6 inch tolerance (it doesn’t really look like 6 inches of vertical growth since it isn’t straight) but my husband, with such straight and short hair, has a quarter inch tolerance.

I shave it off once it starts looking like shit

Quarterly

I let it all grow in winter for warmth. Once it starts to warm up I start shaving my head twice a week. When the heat of summer arrives I shave my beard off and it gets added to the bi-weekly shaving.

Every 1 or 2 weeks. I buzz the whole thing with #1 guard on the clippers.

No

used to go once a month or so, but then covid lockdowns happened and the barber I liked actually complied with the regulations (which is a good thing), which made it more inconvenient than I though it was worth to get a haircut. At first I figured I’d go back once things started returning to normal, but then that took a while and I never did. So, I haven’t gotten an actual haircut in almost six years.

I did start getting the ends cleaned up every six months or so about a year ago though.

I buzz my head about once a month, otherwise I start to look bald.

Once a month.

It’s actually become a bit of a self-care routine because I go to a Turkish barbers who’ll also do ear hair burning off (nowhere near as intense as you’re imagining), noise hair waxing, and a hot towel cut-throat shave.

I actually like the sensations from them all and I walk out feeling clean and fresh, gives me a monthly little boost of confidence.

I cut my hair when it bothers me. I don’t keep track of the interval.

I bought the proper hardware to cut my own hair, learned how to do the fades. It’s easy to keep it the same length all the time this way.

Mainly I just got sick of paying so much for a 10 minute cut.

Edit: I’m not gonna say it was smooth sailing from day 1 I should add, I buzz cut my failures off as I was learning a couple times lol.

Around 2004 for my last hairdresser haircut, and about twice a year I take a hand span off the end myself. I have my hair long and I eat a lot of protein so it grows quickly.

Beard on the other hand is weekly or thereabouts.

As a woman I get my hair cut every 8 weeks.

I would only cut my hair once a month or later if not for the neck hair. I get a cut once that shit becomes too long.

Whenever my wife complains I look homeless and is willing to spend 20 minutes cutting it for me.

Which is roughly every 2-3 months I think. It’d be less often if I didn’t have a wife and had to pay someone to do it, that shit gets expensive.
