One of the newest trends on TikTok that has been taking over every BookTok girl’s For You Page is the “Wavy Hair Theory.” This theory can best be explained by Betches, who describes the theory as “when you’re in love, you wear your hair in a way that looks more natural, bouncy, and a little bit messy.” This sparked an interesting conversation amongst viewers. What are some examples of this theory and is it accurate?

The most famous example of this theory is in the movie How to Lose a Guy in 10 Days. Andie Anderson (Kate Hudson) is seen at the start of the movie with straight hair. However, as she begins her relationship with Benny Barry (Matthew McConaughey), her hair goes from pin-straight to full waves by the end of the film after she falls in love with him. 

This theory seemingly makes sense as wavy hair is usually associated with being carefree, passionate, and determined, all signs a girl has fallen in love. A girl letting her hair go a little wild and natural is a sign she is also comfortable with herself, as well as comfortable with her partner.

This theory can also be scientifically explained as well. When you fall in love with someone, you will produce more stress hormones. These hormones can impact the appearance of your hair. Your body will also produce more oxytocin. Oxytocin, according

to osmosis.org, can help improve your mood and make you feel more “attached” to your romantic partner. It is known as the “love hormone.” It can also stimulate hair follicles, making your hair look more wavy or voluminous. 

Now, this isn’t to say every single girl who falls in love will happen to have naturally wavy hair and the loose curls will begin to appear when sparks begin to fly. There are so many different hair types, and the way we style it does not always reflect how we’re feeling. However, it is an interesting pattern that many have noticed in their lives and movies/TV shows. 

So, if you happen to see some waves appearing in your hair when you fall in love, you now know there is a reason why. Alongside that, if you find yourself putting down the hair dryer and flat iron and instead letting your hair fall naturally, you could just be part of this theory.
