12 Best Hair Serums to Fight Off Frizzy Hair

When summer rolls around, most people start thinking about vacations, happy hours, and days spent sunbathing by the pool. I, on the other hand, spend a good amount of time thinking about how I’m going to keep my hair from frizzing up due to the heat and humidity. Since frizz is primarily caused by dryness and humidity, it’s important to stock up on products to help lock in moisture. Whenever my conditioners, masks, and creams aren’t enough for my hair to fight off the inevitable puffiness that comes with the summer heat, I reach for a serum for an extra boost. Similar to serums that we use for our skin, hair serums provide a protective layer as somewhat of a safeguard against the elements, or the excess styling and manipulation that lead to dryness and frizz. “Moisturizing your [hair] is key! Dryness and splitting is the number one issue that causes tangles, frizz and brittle ends,” says professional hairstylist, Sidney Sha’don. “Hair serums coat the hair creating a sleek polished look. Some help reduce frizz and prevent heat damage.”

When used regularly as a part of your hair routine, serums help your hair to retain moisture leaving it shiny, hydrated, and defined. To ensure that we all will be able to spend ample time outside this summer sans frizz, I scoured the internet and consulted with hair experts to bring you a list of the 12 best hair serums for frizzy hair.

Super Skinny Serum

Paul Mitchell products were always a part of my hair routine as a kid and this product recently reminded me why. This cult favorite product is everything you could want in a serum.

My coily hair is prone to frizz especially in humid weather, and I can always count on this serum to keep my hair looking sleek.” — Tasha Nicole Smith, Beauty Assistant

This has been a classic for over a decade for a reason, and is one of Amazon’s most beloved hair serums.” — K.H

What ingredients should I look for in a good serum? What ingredients should I avoid?

"A lot of hair serums have many ingredients in them, but it’s best to do your own research and find what suits your hair needs. If you're someone who’s looking to use a hair serum that is more natural I would suggest looking for key ingredients like argan oil, coconut oil, marula oil, or aloe vera. Ingredients I would recommend avoiding are parabens and sulfate. They can dry and strip the hair from its natural moisture," says Sha'don.

What techniques do you suggest when using serum to help tame frizzy hair?

"Applying serum when wet is best because your cuticles are open and it will allow your hair to retain moisture," says Sha'don. "Also, using a silk scarf or investing in a silk pillowcase will also protect your hair from frizz."
