High in protein, egg shampoo is excellent for fine, thin, or oily hair. The protein works to strengthen the hair shaft, and adds body and texture to the hair. Plus eggs are packed with vitamin A, D, E, B12, biotin (often touted as the ‘hair growth vitamin’), iodine, selenium, and pantothenic acid (you hear in shampoo adverts) – all great for shiny, healthy hair. I am not sure how much of this gets absorbed in 5 minutes of washing, but it works really well as a shampoo. It makes your hair clean, shiny and healthy. And minus the harsh detergents and preservatives, which is awesome.
