To clean hair and give it a super shine, whip an egg into tepid water (not too hot or you'll be dealing with a poached egg), then lather it into your hair. Rinse it out with tepid water or that egg will poach right on top of your head. To deep-treat damaged hair, give it a healthy sheen, and cure dryness right down to the roots, use this pre-shampoo conditioning treatment: Mix together 3 eggs, 2 tablespoons olive oil or safflower oil, and 1 teaspoon vinegar. Apply it to your tresses, cover with a plastic cap, and leave it on for 30 minutes. Then shampoo as usual.
