Lots of hair products can leave built-up scum behind on your hair, making it dull, limp and lifeless. Grab a bottle of beer and get to work! Soaking hair in room-temperature beer for 15 minutes helps to rescue your strands in several ways: the alcohol strips away any old, built-up products that have gotten left behind while the natural proteins permeate your hair and smooth down split ends and frizzies. Another tip? The darker the beer (think porters and dark brews like Guinness Extra Stout) the better -- a darker brew has more protein than a light beer.
