I love it because it's a wonderful second-day hairstyle.
It works best with some left over curl in your hair.
You can try it on straight hair, but it's harder to hide your ends.
Or you can do it with wet hair. (Wet ends hide much better.)
Curly ends are the best, though. That way,
if they show, they just blend in with the circular shape.
It's fairly easy. All you need is a brush and a handful of bobby pins. Get brave and try a flirty new look.
