Beer Hair

If I want to use beer on my hair to add shine. What do I do?
Just dump it over my head and just a little hope That misses and hits my mouth? Seriously, do I use Before shampooing it or while in the shower? I have no clue. (Please Disregard my avatar. It is a joke in response to someone's question. I Know It Is Not Representative of the beauty style and category.) Thanks so much!! Also, am I going to smell like a brewery? I'm in a wedding on Saturday.
just pour it on you head
