Beer shampoo adds body and shine without coating your hair in harsh chemicals. You can make your own beer shampoo using any brand you have in the house — all beers act as clarifiers — plus a little bit of your normal shampoo. To ensure that this mixture is gentle, use an all-natural shampoo that emphasizes organic ingredients and essential oils.
Reduce the beer. Pour 1 cup of beer in a sauce pan and heat it over medium heat until it reduces to approximately 1/4 cup.
Let the reduced beer sit in the pan to cool until it reaches a temperature that can be handled easily.
Mix the beer with your shampoo. Combine the reduced beer with approximately 1 cup regular shampoo.
Shampoo your hair as you normally would, rinsing well. You can use beer shampoo on a daily basis.
This shampoo does not need to be refrigerated. An even simpler approach is to use beer as a rinse. First, use your regular shampoo. After rinsing out the shampoo, just pour a bottle of beer on your hair. Let the beer sit in your hair for a few seconds and then rinse it out thoroughly with cold water. Flat beer works best for this.
