Hairstyles for greasy hair don't get easier (or chicer) than this cute ponytail. The style is perfect, because it keeps you looking sleek and professional in the front, but the messy texture in the back is easier to achieve with dirty hair.

First, pull your hair back into a mid-height ponytail and secure with an elastic. Make a small braid from a section of your ponytail and wrap it around the base so it covers the elastic, then pin it in place with bobby pins. Spray your ponytail with a dry texture spray, like BlowPro Textstyle Dry Texture Spray, $19.75, to add extra body so it doesn't look straggly.

A beach-y, braided bun is nothing without a little tousled volume. But how can you achieve that on your limp, unwashed strands?

Create body with an instant volumizer, such as Serge Normant Dream Big Instant Volumizing Spray, $25. (This works with all hairstyles for greasy hair). After applying to your roots, plait one side of your hair into a loose Dutch braid (learn how here). Repeat on the other side, and then gather your hair into a loose, messy bun at the nape of your neck.

And, for the finale, a side braid -- one of the most classic hairstyles for greasy hair. If your hair is oily, Dean says an easy fix is a dry shampoo or root product (try Sachajuan Volume Powder, $35).

Just make sure you're using them correctly. His tip: "Whatever product you use, make sure to work it in after letting it sit for 30 seconds or until all the powder is dissolved from soaking up the oil." He warns not to leave your fingers in the hair and overwork the strands, or you'll just be adding more oil back into them from your hands.

Then, simply pull your hair off to one side and braid it. Use bobby pins to secure any areas that feel like they may fall out.
