FOR ALL HAIR TYPES:
“The [raw] egg is really the best of all worlds,” says Janice Cox, author of Natural Beauty at Home. The yolk, rich in fats and proteins, is naturally moisturizing, while the white, which contains bacteria-eating enzymes, removes unwanted oils, she explains.
To Use: For normal hair, use the entire egg to condition hair; use egg whites only to treat oily hair; use egg yolks only to moisturize dry, brittle hair, Cox says. Use 1/2 cup of whichever egg mixture is appropriate for you and apply to clean, damp hair. If there isn’t enough egg to coat scalp and hair, use more as needed. Leave on for 20 minutes, rinse with cool water (to prevent egg from “cooking”) and shampoo hair. Whole egg and yolks-only treatments can be applied once a month; whites-only treatment can be applied every two weeks.
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.
For Itchy Scalp:
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.
For Limp or Fine Hair:
To add body to hair, reach for an unlikely beauty beverage: beer! The fermented drink contains generous supplies of yeast, which works to plump tired tresses, explains Cox.
To Use: Mix 1/2 cup flat beer (pour beer into a container and let it sit out for a couple of hours to deplete carbonation) with 1 tsp light oil (sunflower or canola) and a raw egg. Apply to clean, damp hair, let sit for 15 minutes, then rinse with cool water. Or add flat beer only to a spray bottle and spritz onto dry hair. “When the liquid evaporates, the remaining protein residue (from the wheat, malt or hops) continues to strengthen and structure hair,” says Belkin. Treatments can be applied every other week.
