You can buy store bought mayonnaise or you can make your own with eggs, olive oil, lemon juice or apple cider vinegar, and coconut oil. Whichever mayonnaise you choose, always remember you can also add other natural ingredients such as olive oil, avocado, or honey to mix a custom cocktail for your hair needs. In fact, specifically adding almond oil and vinegar can help to get rid of lice.
When you treat your hair with mayonnaise, you get the benefit of L-cysteine–an amino acid and powerful antioxidant found in eggs that can give your hair strength, shine and structure. According to the Health and Body Fitness website, L-cysteine not only makes up 18 percent of your hair, but is a keratin- forming substance that increases the hair shaft and hair growth density.
