Main thing is you need to have product in your hair, whether that be mousse, curling gel, root boost, or whatever works for your hair.
Clean, freshly washed hair will not hold a curl.
A set of good-quality curlers work the best, along with having a couple different sized curling irons to fix any strays that didn't curl nicely. It's also useful for touchups throughout the day. Of course,a good quality curling iron will also work best.
And lots, lots, lots of hair spray. Again, good quality salon hair spray is best.
And practice! Do a couple practice sessions at home before the big day.
