Crush a handful of cones and pour a little beer to make a thick paste. Then boil half a cup of olive oil (¼ cup) in a saucepan, add the yolk to the oil, combine it with the cone paste, mix it thoroughly and apply to the hair. The mask should be rinsed off after about 30 minutes. Wash your head with a shampoo, for example a hop shampoo, featured in the recipe below.
