Step #1:
Brush your hair well, then brush it up and away from your face toward the low crown area. Gather all of your hair together and create a ponytail by securing it at the low crown area with a hair elastic.
Step #2:
Split the hair in half inside your ponytail, then twist the right-hand section to the right.
Step #3:
Create a large loop and wrap the ends around the other side. This will be half of your infinity sign. Bobby pin it into place.
Step #4:
Repeat on the other side by twisting the hair slightly to the left, creating a loop, wrapping the ends around the other side, and securing with bobby pins.
