Why Curls Get Frizzier in Summer

The curly crew knows summer has arrived not because of the heat or humidity, but because they wake up one morning and their hair is frizzier than ever, as if they've just stepped onto a tropical beach. If you have textured hair, you know exactly what we're talking about. It can be frustrating, but understanding why it happens is the first step toward managing it.

The Main Culprit: Humidity

Curly hair tends to be drier than straight hair because the scalp's natural oils have a harder time travelling through the twists and coils of each strand. This means curly hair is constantly seeking moisture.

With humidity comes more moisture in the atmosphere, and dry hair absorbs it. These water molecules disrupt the curl pattern, causing the cuticle to swell and lift. The result? Frizz, fly aways, and undefined curls.

Heat Makes Things Worse

Along with humidity, summer also brings higher temperatures. Excessive heat causes the moisture in your hair to evaporate faster, leading to drier hair. Dry hair then absorbs even more moisture from the air, creating a cycle of dryness and frizz.

Sun Exposure Can Exacerbate the Damage

Prolonged sun exposure can weaken the outer layer of the hair, leaving the cuticle rougher and making your hair more prone to frizz. Over time, this can lead to increased dryness, reduced elasticity, and curls that become harder to manage.
