Humidity's Effect on Hair(i.e., Frizz)

It wasn't easy to get something firm on this, but here are some opinions:


What percentage humidity makes hair frizz?

curly hair - probably like 80% or so
curly but straightened hair - probably only like 50 or so
straight hair - around like 95% or so
and straight people with curly hair - I'd say about 60 or so


I have curly hair..which frizzes easily, but because i've lived in Alabama https://www.blogger.com/blogger.g?blogID=3735671552858943317#editor/target=post;postID=4080052159949144004all my life, my hair is use to the humidity and won't frizz easily unless i go to the beach. But if you're looking for a percentage I've heard 75-80% 


if your hair is naturally straight, and I mean pin-straight, it will take anywhere from 50 to 80 percent humidity. If your hair is wavy 30 to 50 percent humidity will more than likely make your hair frizz.


{Looks like I need to keep a log and figure this out for myself} So, starting today:

Forecast: 45% humidity.  Left natural updo, a little hairspray:
