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
To fight flakes—brought on by poor diet, stress and climate, among other factors—try a lemon juice and olive oil mixture in your hair. "The acidity in lemon juice helps rid your scalp of any loose, dry flakes of skin, while the olive oil moisturizes the [newly exposed] skin on your head," says Cox.
To Use: Mix 2 Tbsp fresh lemon juice, 2 Tbsp olive oil and 2 Tbsp water, and massage into damp scalp. Let mixture sit for 20 minutes, then rinse and shampoo hair. Treatment can be applied every other week.every other week.
