I would say....hairspray BEFORE you curl your hair... take a small section of hair, make sure it is detangled, and spray the whole length with hairspray, preferably something with maximum hold or a freezing hairspray (not dripping wet) and then wrap it around a medium barreled curling iron. DONT brush through (brushing through will loosen it to a more natural curl/wave) simply finger style the ends AFTER your hair has cooled completely otherwise the curl might not last as well. Just be careful if you have very light blonde hair. I do, and sometimes when i spray my hair and then curl it, the barrel turns my hair pinkish purple in some places. but i think its a chemical reaction to my curling iron. i hope that works for you. Im much better with makeup than hair but thats how i get that type of curl.
