buahahaha this is my realm of expertise!! (well now it is anyways...)
due to me roaming in rickys(a beauty supply store) about every week i found 2 products that do wonders!!!
#1 moisterize once a week(or more) with L'oreal ...something another.... its about $14 for the bigger one theres also a shampoo to go along with it but I havent tried it

#2 when you get out of the shower from washing your hair use a gel to keep it from frizzing. I use Curls goddess glaze ;D "Curls" also has a line of products...but this is the only one ive used

the curls gel REALLY made a diffrence with the flyaways and the frizz i really suggest it and its not that expensive about $14, and it lasted me 3 monthes, I use it every other day
