The barbie ponytail is having a moment and Ariana Grande has her approval. This elegant and whimsical hairdo can work for all hair types and the best part is that it’s super easy to do. Simply brush your hair back, flatten the front and tie a really high ponytail, wrap around a section of hair on your hair tie to get that extra height and firmness. Finish off the fuss-free look by setting frizz using a hair wax.
