Being an oily ragger myself I stopped buying shampoo nearly three years ago and now just wash my hair in warm water while showering. But once a week I beat an egg, pour it onto my hair and massage it into my scalp. Result – lovely soft and bouncy hair. Follow that with a vinegar rinse and you will be amazed how lovely your hair is. But don’t have the water too hot! Scrambled egg in the hair is not a good look.
