You should shower and then cover it in leave in conditioner while it's still a bit damp, all through your hair. Then section it off into 4 or 5 sections and twist it into big ringlets yourself while it's still damp. Leave it to dry and then run your finger trough the big ringlets and you should have loose curls without frizz. I usually put mousse or spray in mine after to stop them from frizzing and going tight again.
