What you need1 cup of Beer
1 cup of simple shampoo
You can use any beer for this one, even the leftover dregs at the end of a party.
Use a basic shampoo, not something full of chemicals and other additives. Just keep it simple.
Reduce the beer down by simmering it in a pan for 20 mins or until reduced.
Let it cool to room temperature and add it to your shampoo.
You can pour this straight into a recycled shampoo bottle or for fun pour it into a beer bottle and secure with a cork or bottle top.
