Why Does Humidity Make My Hair Curly?

If you’ve ever straightened your hair and stepped into a steamy shower, you know what humidity can do to your ‘do. Whether you’ve just flat ironed your hair or have a big event coming up, make sure you read this article! We’re going to examine the reason why humidity makes your hair curl and walk you through what you can do to stop it.

This Is Why Humidity Makes Your Hair Curly

Humid air holds more water than your hair does. Water molecules want to create balance, so they’ll move from the oversaturated air into your dry hair. Once the water molecules are inside of your hair, they reshape the hydrogen bonds holding your hair together. As a result, your hair gets frizzy, and in some cases, curly. The chances of your hair curling up in response to humidity increase if your hair is naturally curly. 

How to Fight Humidity

Now that you know why humidity makes your hair curly, you’re probably wondering what you can do to prevent it. Luckily, there are a few easy ways to stop humidity in its tracks. We’ll take a look at them below.

  • Use frizz or humidity-blocking products - Both humidity and frizz-blocking products create a protective layer around your strands. This layer prevents moisture from reaching your hair and can help you maintain a sleek style for much longer than you would have otherwise. Many serums use silicones, so make sure you’re eliminating product buildup with a monthly clarifying treatment.

  • Moisture your locks - The drier your hair is, the more it will react to the water in the air. If you want to fight frizz, give your strands plenty of moisture. Use hydrating shampoos, conditioners, creams, and lotions. You should also seal the water into your hair with an oil or serum.

  • Use ceramic, tourmaline, or ionic technology - Ionic, tourmaline, and ceramic hot tools bombard your hair with negatively charged ions. This charge seals your cuticles and helps lessen your chances of developing frizz.

  • Get a trim - If you notice that most of your frizzy curls are at the ends of your hair, it’s likely a sign of damage. As the oldest parts of your hair, your ends are the most likely to show signs of wear and tear. As a result, they revert much more quickly. You can prevent this by getting regular trims and keeping the rest of your hair healthy.

  • Wear a humidity-proof hairstyle - When it comes to fighting frizz, it's better to pick and choose your battles. If it’s a particularly humid day, wear a hairstyle that protects your strands from the air around them. That may mean wearing a chic hat or throwing your hair into protective braids, twists, or buns.

Your battle against frizz can feel like a waste of time. However, once you find the right products and styling routine, you’ll be able to keep your hair sleek in even the most humid weather. That said, we hope this article has given you all the answers you were searching for!
