It's unbelievably simple. I use an old Conair Ion Shine set, but their more recent Instant Heat ceramic flocked rollers are very similar.
Starting with dry hair, curl all your hair in one direction, away from your face. I use the bigger curlers around my face, tapering off with the smallest size curlers at the back.
Set your hair for 10 to 30 minutes (depending on how tight you want the curl; I like 30, so they can slowly fall down throughout the day), and finish with some hair serum. I use Nick Chavez Angel Drops.
Try not to hate on my cheesy voiceover too much, k? Hope I've inspired you to buy some hot rollers!
