leave in conditionerfrizz ease when you washapply iron oil sprayinvest in some GHD Ceramic straightenersyou can also get it chemicaly straightned at the hairdressers, but I'm sure you look lovely dear.
have you used a flat iron? I use a high gloss instant shine,(citra-shine) I get it at wal-martI put that in after shampooing and towel dry, then add a dime size let dry naturallyyou can blowdrya little but alot of it causes frizzies.good luck!
