my friends and i are planning a spring break trip to cancun..now people told me its very humid there or is it? when i go out the humidity curls and drops my hair. i have naturally thick cury hair and i put chemicals and sometimes even straighten it with an iron.and it looks great after its up... but as soon as i go outside or to a hot club bam down it goes and it curls and frizz's. it sucks because its a loss of confidence and what not. im aLREADY USING CONDITIONER AND SHAMPOO. What products should i by. my goal is to go out to a very humid place where its hot and look at my hair and it still be standing up like the way it was when i put it up.
