Use your curling iron
The curling iron will help you keep your curls in place. First, isolate a section of hair and comb it through to smooth it. Then, holding the hair section by the ends, clamp your curling iron around it at the root, and slide the rod to the ends.
Then, rotate it to wrap your hair around it. After that, twirl it back to within an inch of the scalp; hold for 30 seconds, gently unclamp the rod and slide it out without uncurling the curl. Let it cool before brushing it out.
