Hair products for curling hair

AnnaRose
So I don't curl my hair very often (because I have naturally curly hair I use mouse and a diffuser most of the time) but I am curling my hair for a wedding (like with a curling iron). I tried it out today and I have this nice halo of friz around my head ? any suggestions on what I can use to fix that? 
​Also, it didn't seem like the curls have stayed in as well this time as opposed to the last time I tried. Last time I took a shower in the morning, let my hair air dry some and then blow dried it the rest of the way. This time I took my shower the night before. Do you think that makes a difference?
