Mayonnaise Has long been used to help dry, brittle and damaged hair. On top of hairstyling tools causing damage, many products—like shampoo, conditioner, hairspray, gel—also contain alcohol which makes dry hair even worse. Surprisingly, it’s the cholesterol in the mayo that helps to soften your hair and reverse damage. Pour a cupful of mayo into a bowl and allow it to sit until it reaches room temperature. Add a few drops of vanilla to the mayo so it smells a little better. Add to the bowl three egg yolks and half a cup of olive oil. Throw 2 bath towels in the dryer to get them hot. Shampoo and condition the hair to get any product build up out! Apply the mixture throughout your entire hair, focusing on the ends. Wrap your head in plastic wrap to seal the mayo mix into your hair. Wrap one hot bath towel around your head for 10 minutes. Switch to the second hot bath towel for another 10 minutes. Rinse the mixture thoroughly out of your hair—if you’re going out, shampoo your hair thoroughly; if not, just rinse the mixture out without shampooing.
Apple Cider Rinse When products and hair chemicals settle on your scalp’s surface, two things happen: they reduce the shine and the mess up your hair’s pH. Hair is just slightly acidic, but most hair products are very alkaline. When product build-up happens, the hair will appear dull, lackluster and damaged. Cleanse your hair and restore its natural pH with an apple cider rinse. Mix one tablespoon of apple cider vinegar with one cup of warm water. Shampoo your hair as normal. While rinsing the shampoo out of your hair, pour the vinegar through your hair as well. Leave the vinegar in your hair for several minutes before rinsing out.
For All Hair Types The [raw] egg is really the best of all worlds. The yolk, rich in fats and proteins, is naturally moisturizing, while the white, which contains bacteria-eating enzymes, removes unwanted oils. 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. 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. 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.
