How to get selena gomez and miley Cyrus hair.?

Because it does change everytime, I can only give you one way to curl hair. I do mine with a 1-inch barrel curling iron. Once it's heated, instead of starting from the bottom of my hair and rolling the curling iron to my scalp, I start at the top. Roll or twist your hair around the barrel (starting at the hair at the scalp and roll until the entire piece of hair is rolled) and clamp it there for 10 seconds. Don't do big chunks of hair at a time. If you have layers, do it layer by layer and only do relatively small pieces of hair at a time.Then unclamp the curling iron and if it's done right, you should have nice, bouncy, big curls.
