Determine Curling Iron Size Needed for 1950s Hairstyle

"Hi, my name is Jan Cuni, I'm a professional hairstylist and hair colorist. I work for Plaza Salon in Paramus. I'm here on behalf of Expert Village. Some people like tiny smaller curls and some people like big curls. For long hair you have to use a bigger curling iron. For short hair you have to use a smaller size. It makes the curl look better when it's a big curling iron with the long hair. Now I get another section and spray it again."
