Treatment for hair with yogurt

For Dull Hair

Styling products (as well as air pollution) can leave a film that both saps moisture and dulls shine—but dairy products like sour cream and plain yogurt can help reverse this damage. "Lactic acid gently strips away dirt while the milk fat moisturizes," says Lisa Belkin, author of The Cosmetics Cookbook.

To Use: Massage 1/2 cup sour cream or plain yogurt into damp hair and let sit for 20 minutes. Rinse with warm water, followed by cool water, then shampoo hair as you normally would. Treatment can be applied every other week.
