Lena loves lager: I love your site. Thanks for giving intelligent and scientifically sound beauty advice, something that seems to be woefully scarce. So here’s my question: I have heard about people using flat beer as a rinse for their hair, and also I’ve seen shampoo from Lush with beer as its featured ingredient. I’m wondering what exactly it is that people claim beer accomplishes, and whether it really does do what they say. Thanks!
The Right Brain pours a cold frosty reply:
Believe it or not, beer really is good for your hair! Here’s how it works:
It’s about 2 am and the guy at the bar who’s been ogling you over his last 6 or 8 bottles of Bud Light staggers in your general direction. He moves in for kill, getting up in your face and suavely blurting out: “Gee yer hair looksh aweshum! *Hic*.”
That kind of drunken compliment is about the most benefit your hair will get from beer.
But all kidding aside, is there any plausible reason to put beer in your hair? Let’s take a sip, shall we…
Beer buzz
There are several theoretical arguments for putting beer on your hair. Unfortunately, none of them can hold their liquor.
Beer contains protein which is good for strengthening hair.
While beer does contain corn, wheat, or rice protein it’s not in the correct form to deposit on your hair and form a stengthening film, which is how proteins work.
Beer has a low pH which can tighten the cuticles and make your hair shiny.
The pH of beer is low due to dissolved carbon dioxide but it’s not enough to make a difference to the condition of hair.
Beer contains herbs known as hops which are natural astringents that have beneficial tightening effect on the scalp.
Hops are present at a very low level and are not in contact with your skin long enough to have a measurable effect.
Beer contains alcohol which is good for removing dirt and grease from hair.
The cleansing power of the relatively low amount of alcohol in beer pales in comparison to shampoo.
The Beauty Brains bottom line
While beer won’t HURT your hair (other than making it smelly), it certainly doesn’t provide any technical benefit. We say save it for drinking!

啤酒给予的美丽
丽娜爱啤酒：我喜欢你的位置。谢谢你给予我明智的以及听起来很科学的建议，这些建议似乎少得可怜。所以这里我有几个问题：我听说人们用冲淡的啤酒来清洗他们的头发，我也看见过高档的洗发水以啤酒作为成分来吸引人。我想知道人们真让想要啤酒做到什么，以及啤酒是否可以真正做到他们想要的。谢谢！
正确的大脑冷淡地回答：
信不信由你，啤酒真的有益于你的头发！这里将告诉你它是怎么起作用的：
两点钟的时候，那个家伙越过他剩下的发着眩晕的光的6瓶或者8瓶酒朝着你这边的方向抛媚眼。他周旋于厮杀，抬起你的脸突然温和地说道：“啊，你的头发看起来很漂亮！嗝。”
那种酒醉的赞扬是关于对你头发最有益的东西是来自啤酒。
但是排除玩笑，真的有某种似是而非的原因让你把啤酒放到头发上么？让我们喝一口，怎样。。。
啤酒的自述
把啤酒放到头发上有几个理论根据。很不幸，他们之后没有一个能保留住自己的汁液。
啤酒含有固发的蛋白质
虽然啤酒含有玉米，小麦或者大米的蛋白质，但是这种蛋白质起作用的形式，也就是沉淀在你头发上从而形成加固膜的形式是不正确的。
啤酒的PH值比较低，能使头发表皮变紧从而使你的头发更有光泽。
啤酒的PH值低归因于溶解的二氧化碳，但是这不足够于改变头发的条件。
啤酒含有所谓的富有收敛剂的蛇麻草，这有益于使头皮紧密。
蛇麻草很少会出现，它也不能长时间于你的皮肤接触达到想要的效果。
啤酒含有有益于除去头发上的污垢和油脂的酒精。
啤酒的这种相当低的去污能力远远低于洗发水。
美丽大脑概要
虽然啤酒不会伤害你的头发（除了让头发有臭味），当然它也不会提供技术方面的利益。我们还是剩点来喝吧！
