Mix together: a tablespoon of crushed hop cones, chopped soapwort root and chamomile flowers. Pour 2 glasses of beer over the mixture and heat over a low heat, covered for about 10 minutes. The whole mix should then be strained (it is a shampoo, so it must have a clean and clear consistency, free of all kinds of fluff that could settle on the hair). You should wash your hair with this decoction.
