If there’s one thing we hate about summer weather, it’s humidity.

Humidity equals frizz, and frizz can be the worst.


Humidity is one of the top causes of frizz, it can also be caused by a few unexpected things (such as hot water, for example, but more on that later).

“Frizz is caused when hair is dry and lacks moisture,” 

“When your hair is dry, the cuticle is rough, and when the weather is humid, it’s the perfect recipe for frizz.

The outer layer of the hair takes in the moisture from the air, causing the hair to swell and frizz.”


The cuticle is made up of what looks like “little shingles,” adding that the cuticle layers should ideally lie flat, but they open up when damaged or exposed to moisture.


With countless anti-frizz products on the market, you’d think it would be easy to keep frizz at bay. But sometimes it feels like no matter how much stuff you put in your hair to stop it from going all frizzy on you, nothing works.


Don't get us wrong; we're all about embracing the volume and softness that comes with frizzy curls. But sometimes we appreciate the option to enjoy a more defined look, even when humidity levels are off the charts.

It's no secret that sticky summer air leads to frizz, but it's not the only culprit behind the curls that won't hold up their shape. If you find yourself  asking, "why is my hair so frizzy?" take a look at these five common issues -  because learning what causes frizzy hair is the first step to knowing how to tame it. 


1. Over-Cleansing
Just like skin, hair has a natural protective barrier that helps keep essential moisture inside and acts as a shields against the elements. Aggressive cleansers strip curly hair of this barrier, leading to dryness, breakage, and frizz. To keep your curls frizz-free, choose a sulfate-free shampoo and avoid washing your hair every day. Instead, co-wash or simply rinse your hair with water between shampoos, and only cleanse when your scalp is actually dirty.

2. Dryness
Like a sponge, hair that’s thirsty will try to soak up moisture wherever it can find it. This means that the drier your hair, the more susceptible it is to absorbing frizz-causing humidity from the atmosphere. Keep your curls well-hydrated by using a hydrating conditioner made specifically for your curl type.

3. An Open Cuticle
Curly hair curving shape means its cuticle layer is naturally raised, with gaps in between the overlapping cells. These gaps allow moisture and nutrients to escape, and humidity to enter and frizz to begin.
To ward off frizz and help curls look healthy, hydrated and shiny, you need to seal the hair’s cuticle. Acid rinse, conditioners and daily moisturizers can help with this, including technology that helps to fill in gaps in the cuticle to defend against frizz.

4. Damage
Damage from environmental aggressors can compromise your hair also. Heat, UV rays, and even friction from combing and brushing also can make your hair weaker and more prone to becoming frizzy. To prevent damage, use a daily leave in moisturizer to protect your hair from sun, styling, and tangles.

5. Humidity
Nothing makes curly hair turn frizzy faster than rainforest-like conditions. That’s because humidity disrupts the hair’s internal hydrogen bonds, causing curls to shrink, frizz, and lose their definition. Luckily, the right anti-frizz styling products can also give you great control of the frizz.
