Celebrity Hairstylists and Trichologists Explain Why Your Hair Is So Frizzy and How to Prevent It

It could even be due to the type of towel you use

Frizzy hair can be a relentless beauty challenge, turning even the sleekest styles into unruly chaos. And you might be wondering why is my hair so frizzy? Whether caused by humidity, heat damage or lack of moisture, managing frizz is a common struggle that requires targeted solutions. Ahead, we explore the causes of frizz and share expert tips and must-have products to help you achieve smooth, manageable hair every day.

Why is my hair so frizzy?

Hair gets frizzy primarily due to a lack of moisture, says Helen Reavey, board-certified trichologist & founder of Act+Acre. She adds, “When hair is dry, the outer layer (cuticle) lifts, allowing moisture to pass through and swell the hair strands, causing frizz. Humidity can exacerbate frizz by increasing the amount of moisture in the air that interacts with the hair, especially for those with high porosity hair (your cuticle layer is more open).”

In addition, you may notice that curly hair tends to be more frizzy than those with straight hair. Celebrity hairstylist Gregg Giannillo explains, “Hair with a curly texture that is dry has a rougher cuticle than straight hair. In humidity, water in the atmosphere is attracted to dryer hair which makes the cuticle lift more, exposing the rougher texture.”

Are there certain habits that make hair become frizzy?

According to Anthony De Los Santos, owner and founder of DOLO New York Hair Studio, there are three major causes of frizz: Over-washing, excessive friction and styling habits. To be more specific, Reavey tells us that over-washing while using harsh shampoos can be drying and contribute to frizz. That’s why it’s best to not to use hair products with sulfates, silicones, alcohols and fragrances.

When it comes to styling, “Frequent use of blow dryers, flat irons and curling irons can damage hair and lead to frizz,” says Reavey. And remember to use a heat protectant if you are applying heat to your hair often. In addition, Giannillo says, “Towel drying the hair by rubbing it too hard and disrupting the curl pattern enhances frizz.”

How to prevent frizzy hair

1. Try a microfiber towel

Swap a regular towel for a microfiber one, like Act + Acre Microfiber Hair Towel. The gentle fabric dries hair to reduce excess friction to prevent frizz and cut drying time in half.

2. Incorporate heat protectant

Using a heat protectant, like Kérastase Genesis Heat Protecting Leave-In Treatment, prior to styling with hot tools creates a protective barrier between hair and the iron. Limit heat styling by using heat tools sparingly.

3. Apply deep conditioner

Giving hair some TLC in the form of a deep conditioning hair mask once or twice a week will restore moisture. Formulas rich in glycerin and shea butter will add extra hydration and nourish ends damaged from heat. Try: Brazilian Blowout Deep Conditioning Masque.

4. Use a leave-in treatment

Apply a leave-in conditioner, like OUAI Leave-In Conditioner, to target the ends of your hair. These products help to hydrate, strengthen and reduce frizz and breakage.

5. Nourish with hair oil

Use hair oil to restore hydration to dead or dry ends. Look for options made with argan oil since it protects the hair from UV rays while improving shine and reducing frizz. One we will like is Olaplex No. 7 Bonding Frizz Reduction & Heat Protectant Hair Oil.

6. Moisturize with a serum

Applying a hair serum daily will ensure the scalp stays hydrated, such as Act + Acre’s Stem Cell Scalp Serum or COLOR WOW Pop + Lock Frizz Control + Glossing Serum.

7. Rinse hair with cool water

“Finish your shower with a cool rinse to help seal the hair cuticle,” suggests Reavey.

8. Keep hands off of hair

“Avoid touching your hair – the more you touch it, the more you disrupt the cuticle and encourage frizz,” notes Reavey.

How to fix hair that’s already frizzy

Giannillo says, “Hair that’s already frizzy is always in need of more complete moisture. The humidity in the air is just enough to disrupt the curl pattern and the cuticle layer, but it’s not enough to hydrate.” He suggests adding a cream, like OUAI Anti-Frizz Crème, or serum to already frizzy hair helps reduce frizz by increasing moisture.

For curly hair: Rehydrate, add moisture and then apply a styling product with hold. One that fits the bill is: dae Cactus Fruit 3-in-1 Styling Cream.

For straight or styled hair: Add a lightweight serum or wax, like Kitsch Hair Wax Slick Stick, to reduce frizz.
