Egg white and lemon mask

The issue: Grease. If you are prone to greasy hair, an egg mask can work wonders, says Saltzman. Stick with just the whites, which have protein enzymes that help remove excess oil.

Ingredients: 1 egg white, juice from half a lemon.

Directions: Smooth over hair from roots to ends and leave on for 30 minutes to an hour — longer is better. Rinse with lukewarm water, not hot!
