Helmet in Thailand

I'm headed to thailand at the end of the week and was getting mostly packed tonight and wondered about a need for a helmet. I know most routes are probably climbed a lot but we are planning to do a few multi-pitch routes while we're there. I wasn't planning to bring one, but should I?

Thanks

nope, unless you usually wear one while climbing sport, then maybe

Do you value style or your brain more?

Thanks for the replies. I don't usually wear one for sport so I guess I'll be leaving the helmet. I'm only taking a carry on pack with climbing gear and cloths so helmet gets bumped not for style but for space.

Unnecessary. Lots of the multipitch routes in tonsai and railay need two rope raps, FYI.

I left tonsai on Thursday for the states, would go back tomorrow.

on the multipitch routes you'll need a prusik more than a helmet, but sometimes stalagtites come out of nowhere and those are good times to have something between your head and the rock.
ps. you will have a blast! if you're headed to tonsai, make sure you climb king cat, huminality, narsilion, nut cracker, lion king, missing snow... ok i should stop-- i could go on and on
