It is true that not all of us are blessed like Ariana with huge, voluminous, long, thick mane cascading over our back, but this should not stop you from repeating this look if you are crushing on it. Faux pony tail extension will do perfectly fine, as you can conceal the clip with your own hair. Faking is more than justified for this level of glam. Collect your hair and tie it in a high pony tail on the crown. If you are using extension, clip it at this stage. Take a section of your hair, wrap it around elastic (or clip) and secure it with bobby pin. Creating loose curls with curling iron is optional.
