When you just add a shot of vodka to your deep hair conditioner and apply it, it will lower your hair’s pH which helps the cuticles to close and reduce the frizz. Apart from that, just a tablespoon of vodka can be mixed with a cup of water for using it to rinse your hair after shampooing and conditioning. This eliminates product build-up from the strands and scalp, making your hair shiny and lustrous!
