We’re quick to write off most beauty myths as total fabrications—like that one about toothpaste causing chemical burns. But lo and behold, some of the craziest beauty-related "urban legends" are actually true. Go ahead and file these fables under "fact" from here on out:
Tight Buns and Ponytails Can Make Your Hair Fall Out
Any hairstyle that causes tension by pulling at the scalp and root can lead to scarring hair loss, which means it's not going to grow back. Sub out your regular topknot with one of these loose, pretty hairstyles to save your strands.
Rubbing Your Eyes Causes Wrinkles
Rubbing your eyes doesn't directly cause wrinkles, but the pulling motion causes the thin, delicate skin around the eyes to crease back and forth, which leads to the appearance of premature aging over time. You're not going to develop a web of crow's feet from rubbing your eyes once, but we wouldn't recommend making a habit of it.
Rinsing Your Hair With Beer Can Make It Thicker and Stronger
The barley and hops used to brew beer are rich in vitamins and proteins that help hair appear thicker, stronger, and shinier. Meanwhile, the alcohol acts as a cleansing agent. While you can't make each individual strand permanently thicker, beer works to swell and widen the hair shaft until your next wash—so as far as thickening products go, it's among the best (and cheapest!).
Certain Foods May Cause or Worsen Acne
A diet full of greasy foods and chocolate, long regarded as "acne-causing foods," isn’t good for your body—but they don't necessarily mess with your skin. The truth is, there isn't a definitive list of foods proven to cause acne. But because everyone's body reacts differently to different foods, something you're eating could be to blame for your breakouts. Keep track of your diet, and take note when you eat something that causes pimples or irritation—you might begin to notice a pattern.
