Many of the Belters in the Expanse TV series wear mohawks and beards.
Naomi has a mohawk.
Miller has kind of mohawk, more like a lot of hair that flops over one side.
I've seen many minor characters with mohawks.
Amos sometimes trims his beard close, and sometimes wears it longer.
So do many others.
Belters tend to have personal vac-suits. Many in the UN navy and Martian navy have government-issued spacesuits.
Wouldn't beards and mohawks get in the way of space helmets?
You'd think they would be as clean shaven as Prax Meng and with hair as short as his.
Why do many people who travel in space have beards and mohawks? Especially the Belters. Is there something about hair and beards in Belter culture?
I've only seen the TV series, which hasn't answered this, so if you have answers from the books, that would help.
