Step 1: Separate your hair into thirds: a bottom layer, a middle layer and a top layer. Twist the top two-thirds of your hair up into a clip. Split the bottom third in half into a right side and a left side.
Step 2: Spray the bottom layer with a holding spray like this one to help your curls keep their shape and to protect your hair from heat damage. (Repeat this step before curling each layer of hair).
Step 3: With a 1.5" curling iron, curl the bottom layer by rolling sections of hair up. Hold the curling iron parallel to the ground for about 10 seconds and release. Repeat all around your head.
Step 4: Let down the middle section of your hair. Again, split this layer in half into a right side and a left side.
Step 5: To curl this layer, take sections of hair from the left side and curl them by rolling under until the curling iron is close to your head. Then hold the curling iron perpendicular to the floor for 10 seconds. (For the right side, follow the same steps except curl sections of hair by rolling up.) Slowly pump the curling iron to release each section of curled hair.
Step 6: Let down the last top layer of your hair and split into a right and left side. Repeat step 5 -- remember, curl under on the left side (as Stacy's doing above) and curl up on the right side.
Step 7: Hold each curl close to your head for 10 seconds or so. Gently pump to release each curl.
Step 8: Spray curls with hairspray for extra hold.
And here you have it -- pretty party curls for all your holiday parties this year :)
