Oily or Greasy Hair

"Used properly, [cornmeal or cornstarch] is an inexpensive way to remove oil and grease," says Belkin.

To Use:
Pour 1 Tbsp cornmeal or cornstarch into an empty salt or pepper shaker and sprinkle onto dry hair and scalp until you’ve used it all. After 10 minutes, use a paddle hairbrush to completely brush it out. Treatment can be applied every other day.
