Hot weather, sun… and frizzy hair? Yeah.

If you live in a humid climate, the summer weather doesn’t just bring good things, it can also cause frizz. Frizzy hair can be frustrating, especially when nothing seems to tame it.

But as annoying as frizzy hair can be, most of us don’t know exactly what causes it, which means we don’t know the best way to deal with it. But don’t worry, we’re here to answer all your questions.

Hair cuticles are made up of small shingles that protect the hair strand from the elements.

“When examined under a microscope, a healthy cuticle lays down smoothly, like the scales of a fish,” says Steve Waldman, director of technical training at Hair Cuttery Family of Brands, a chain of service hair salons. complete. Beneficial hydration from the natural oils produced by your scalp helps maintain those shingles in healthy hair.

But, he says, “as hair becomes dry and damaged, it looks like a pine cone: open, rough and spiky.”

When opened and damaged like this, beneficial moisture can leak out of the hair shaft as moisture from the air enters the hair shaft, causing it to swell and change shape. In other words, it gets frizzy.

Do some people have naturally frizzy hair?

In short: yes.

Some people have naturally curly hair, which is drier because the natural oils produced by your scalp can’t travel along the hair shaft as well as straight hair. As a result, they have natural frizz, which is most noticeable when the individual hairs don’t bind together to create a defined curl.

However, everyone’s hair can get frizzy even if it’s straight. But people with straight hair tend to notice it more when their hair is damaged, dry, or when it’s very hot outside.

In a word: drought.

Many different factors can dry out your hair and exacerbate frizz:


That’s why your hair gets frizzy on a hot, humid summer day (or when you’re on vacation somewhere hot).

“The dry cuticle becomes rough and open to moisture,” says professional hairstylist Monica Davis. “As a result, a humid environment makes the hair too dry frizzy [because] the outer layer begins to absorb moisture from the air and swells.

Wash your hair in very hot water

Washing your hair in very hot water can have the same effect as humidity. This, Davis says, also stresses your hair and scalp, which produce beneficial oils.

That is why it is best to wash your hair with lukewarm water.

Products for hard hair

“Chemicals or harsh products strip hair of its natural oils,” says hairstylist Kim Kimble. “Your natural oils smooth the hair [so] getting rid of it completely can make your hair frizzy.

Harsh hair products can include:

“Over-lightening — or bleaching — and coloring hair with formulas that are too strong with a high ammonia content can damage the surface of the hair, make it rough to the touch, rob it of shine, and create frizz,” Waldman says. .

Heat styling

“Hot styling tools always damage your hair,” says Davis. That’s why it’s best not to use them every day.

Also, she says, if you use heat styling, look for conditioners, oils or sprays that help minimize heat damage before and after styling.

Washing hair

When you wash your hair every day, you strip your hair of the natural oils it needs to be healthy.

“There’s really no need to wash your head more than two to three times a week, depending on your hair type,” Davis says. “Otherwise you break the natural balance with the shampoo, especially if it’s foamy.”

Dry your hair with a towel

“The friction created by nylon-bristle brushes and rough towel-drying your hair can also ruffle the cuticle, causing annoying frizz,” Waldman says.

Instead, blot your hair when drying with a towel and use softer brushes.

You can fight frizz by using moisturizers, conditioning masks, or serums that protect and smooth your hair, Kimble says. You should also use mild shampoos or detergents.

In addition, these steps can also help you:

  • Reduce heat styling.
  • Use lukewarm water to wash your hair.
  • Don’t wash your hair too often.
  • Use conditioner or masks.
  • Avoid harsh products.
  • Use a microfiber towel to dry your hair.
  • Switch to a boar bristle brush.
  • Use an anti-frizz product if you live in a humid climate.

Here are some products you can use to try and fight frizz:

1. TRESemme Keratin Smooth Shine Serum

“With this remedy, you can protect curly, straight hair from excessive heat,” says Davis, so it’s a great spray to use before blow-drying or heat styling your hair. “It also seals the cuticle and makes it much less likely that your hair will get out of control when you go out.”

2. Briogeo Farewell Frizz Smoothing Shampoo

Made with natural oils to lock in moisture and protect against humidity, this shampoo not only cleanses your hair, but also fights frizz in all hair types. It also contains no harsh sulfates, silicones, phthalates, parabens, DEAs, or artificial colors.

3. TSD Hair Flower Extract Conditioner

“Protein and keratin are frizzy hair’s best friends,” Davis says. “You can use this conditioner from TSD to close the cuticle after washing your hair.” The conditioner also helps detangle hair, making brushing easier.

4. Silk 18 Holistic Maple Conditioner

This conditioner is specially designed to moisturize dry hair and revitalize your scalp. With natural ingredients including jojoba and argan oil, it will help tame your frizz and keep your hair shiny and smooth.
