Regis Design Line has a flat iron spray called ';Get it pressed';. It will help keep your hair from getting damaged when you flat iron it and will keep it smooth even if the weather takes a turn for the humid side. You can find it at any Regis salon and it isn't very expensive.
many people i know recommend garnier fructis' leave in conditioner anti-frizz serum because it coats your hair strands, makes sure it doesn't frizz, and keeps your hair protected.
There's this stuff called iron gaurd, or something like that. It's by CHI.
