Egg yolks contain protein and moisturizing properties that can help the health of your hair and scalp, though it is vital to consider your hair profile when considering egg yolk washes. For instance, while egg yolks contain lecithin (a natural emulsifier) that helps to remove some dirt and oils, the cleansing power is not like that of a surfactant so those with oilier profiles may find these washes to be insufficient. If you do choose to experiment with egg yolk washes, we recommend using this method infrequently and to still have your regular and sulphate shampoos on hand. Additionally, you can try using egg yolks as part of a hair or scalp mask in a pre-shampoo treatment instead.
