Have a model you can practice on before you destroy your own hair :)
Get a thick group of hair
Keep curling iron on hair for 4-5 seconds so it's not a tight curl
LIGHTLY comb out
Gather a large amount of hair on the top of your head
Use a comb and back comb the thick piece of hair you grabbed
It should look this bad in the beginning!!
Comb out gently until you reach the height you want
Wow! Look at that hair!
Big hair always beats flat hair:)
