Keeping hair straight in the humidity?

Hey everyone!

I'm going to be going to Japan soon (couple of months) and I just want to find out how do you people keep your hair straight in the humidity?

I have a big frizz problem (if I do not use the right products). Like after I straighten my hair, it gets frizzy if I don't put on any finishing serums, but I know that Japan is SUPER humid! How do I combat the frizz problem there? I also sweat a ton as well!

I know in the fall-winter months the climate is liveable, but the summers are crazy hot.

So please, if anyone has any product recommendations - that'd be great!

Thanks!

Are you black/African American by chance?

shukumou kyousei or a straight perm are your only options

the humidity in late spring through til mid summer is horrible. the air gets so wet it's like it's raining without there being clouds in the sky.

your hair will explode if you don't have a straightening treatment like i mentioned.
