Beer becomes flat by releasing the carbon dioxide it creates. It’s important that the carbon dioxide is gone from the beer when using it to treat hair as carbon dioxide combined with water can create hard water or water with a high mineral content.

As well, hard water causes the scales on each hair to stand up, making your hair look tangled and tough. [2] X Research source

You can transfer your flat beer into a closed container or bottle and bring it with you into the bathroom or somewhere you can easily reach for while in the shower.

Beer is also very beneficial for your skin as beer sediment or brewer’s yeast helps reduce sebum production and control oily skin on your face or scalp. You can also try dipping the ends of your hair with beer first, letting it set in your hair for about 5 minutes before rinsing your entire head with beer.

Consider using raw apple cider vinegar rather than commercial vinegar. Raw vinegar is not distilled, heated, or clarified. Raw vinegar has much of the good bacteria, nutrients, and enzymes needed to improve hair texture. You can mix 1 to 2 tablespoons of apple cider vinegar to 8 ounces (250 mL) of water instead of beer and treat your hair the same way you would with a beer wash. It’s best to only use a vinegar rinse a few times a week. If used everyday, it can be quite drying for hair.
