Hair Theory: What is It About?

Learn more about the trend that has garnered over 300 million views on TikTok.

If you’re an avid user of the social media platform TikTok, you may have encountered videos of women looking at the camera with their hairstyles changing every second. These are TikTok users testing the hair theory. According to this theory, the way you wear your hair influences how you look and how others see you.

Hair Theory may not be backed by science, but TikTok users are jumping on this trend, with #hairtheory now having 381.6 million views on the social media platform. It may not even be entirely without merit. According to an article in the journal Cosmetics, hair plays a role in one’s “self-perception of beauty.” Hence the continued interest and investment in hairstyling and hair care products that aim to enhance hair appearance.

We took a look at a couple of videos testing hair theory and shared what we think about each hairstyle. Check out our thoughts below.

The Hair Theory Experiment

First, let’s start by saying she looks gorgeous in her long, dark brown hair! The color adds warmth to her skin tone. Plus, it also gives her look a celebrity vibe.

Her first hairstyle—slightly tousled and center-parted—exudes a soft, laid-back vibe. On the other hand, a neatly combed down-do (with hair tucked behind her ears) creates a sleek and elegant look. Then, both the pigtails and twin braids add a childlike and playful touch, while the messy blowout and half-updo look relaxed but sultry at the same time. And last but not least, the messy ponytail spells “girl next door”—friendly and approachable.

Now, let’s check out another video. Don’t we just love the volume of her hair? It makes her locks look soft and bouncy. No wonder she looks effortlessly chic with her long waves. Meanwhile, her low ponytail makes her look ready for school, like a college student on her way to her next class. It’s a simple and practical hairstyle, but her see-through bangs add oomph and make her ponytail trendy.

Her next hairstyle—a messy updo with see-through bangs—makes her look like she’s in for a busy day, so she puts her hair out of the way. However, her fringe says, “I mean business, but I also want to look chic while at it.” In her last hairstyle, we see her holding her hair up in a high ponytail—a versatile hairstyle that makes her look ready for anything.
