The 7 Best Hair Serums For Frizzy Hair

Over the past couple of years, my hair has somehow transformed from chronically straight to wavy in some spots, curly in others, and prone to frizz all over the place. To be clear, frizz isn’t a bad thing (I think it’s kind of cute sometimes), but it does make my hair more difficult to work with. And if you're reading this article, I'm going to assume you've been dealing with something similar. Along with a weekly deep conditioning mask, hair serums have been revelatory. That’s because the best serums for frizzy hair contain ingredients that seal the hair cuticle to protect it from heat, humidity, and other environmental aggressors that all contribute to frizz. In the process, they’ll make your hair look glossy and smooth and feel more moisturized. Many of them smell amazing, too — what's not to love?

Since dry hair is more prone to frizz than hair that's naturally more oily or rich in moisture, the serums ahead contain nourishing and replenishing ingredients like argan oil, shea butter, and coconut oil. In some cases, proteins are added to the mix to help repair damage. In turn, your hair will look smoother and feel stronger, because it genuinely will be.

1. The Best Serum For Thick Hair

A boosted version of the brand’s beloved classic serum, the John Frieda Frizz Ease Extra Strength Serum is spiked with argan oil, coconut oil, and moringa oil — all rich in vitamins, minerals, and fatty acids — to smooth and replenish dehydrated hair. Amazon reviewers report this is a little intense for fine hair, but it’s effective for making thick and coarse hair about a million times more manageable. Apply it to wet hair for best results.

Glowing review: “I use two pumps for my shoulder length, thick blonde hair. I concentrate most of it on the ends and just do a few pats near the roots to avoid product buildup and greasiness. My hair isn't poofy at the ends anymore, lays smooth and retains the natural wavy texture with less frizz without blow drying. When I blow dry and use a straightener, it feels like silk and is virtually frizz free. I don't like using a lot of heat on my hair, so this product is great for my air drying needs as well. I have used it in the past and tried out other products but always end up coming back to this. It just works.”

Key Ingredients: Argan Oil, Coconut Oil, Moringa Oil | Size: 1.69 fl. oz.

2. Editor’s Pick: The Best Serum For Fine Hair

If you have fine hair, look for a flexible spray over a thicker serum, as the latter runs the risk of weighing down your hair — the opposite of the smooth, silky results you’re going for. I like this coconut oil mist from OGX for my own fine hair. Came for the beachy, buttery-coconut scent and reasonable price tag, stayed for the effects: smoothing flyaways and frizz, boosting shine, and maintaining my hair’s movement and fluidity, thanks to nourishing coconut oil and hydrating bamboo extract. Since it’s so weightless, you can keep spraying it on throughout the day, either for the irresistible scent or those smoothing effects.

Glowing review: “This hydrating oil is great. If my hair looks dry and wiry, I spray this great product on and then my hair looks and feels more manageable. This spray is so light it doesn't weigh my hair down.”

Key Ingredients: Coconut Oil, Bamboo Extract | Size: 4 fl. oz.

3. The Best Serum For Curly Hair

Ideally, folks with curly hair need a serum that defines their curls, keeps them light and bouncy, and protects them from the heat and humidity that tries to tamp them down. This Cantu Shea Butter Super Shine Hair Silk ticks all those boxes, thanks to shea butter — the brand’s signature ingredient — which restores moisture and imparts a glossy but natural-looking finish. Despite the ingredient's inherent richness, the formula itself is light and fluid, so it won’t compromise your natural curl pattern. This works beautifully on all types of curls and waves, as well as relaxed and permed hair. For an even more intensive smoothing and hydrating treatment, apply a generous amount to your damp hair, wrap it in a towel (ideally a gentle microfiber towel), and leave it on for 20 minutes. No need to rinse it out.

Glowing review: “I'm an African American woman, and when I flat iron my hair, I usually have problems keeping my hair from drying out. This hair silk works wonders! My hair is nourished and shiny. The serum is absorbed without any sticky or oily feel. Hair is light and flowing. It smells nice when you apply it, but the scent soon dissipates. Good product. I will buy it again.”

Key Ingredients: Shea Butter, Hydrolyzed Silk | Size: 6 fl. oz.

4. The Best Serum For Damaged Hair

Products infused with keratin, which mimics the naturally occurring protein that exists in your hair and skin, can help repair damage inflicted from over-processing, dyeing, and heat styling. This Global Keratin GKHair serum contains a proprietary keratin blend that helps rebuild compromised hair from the inside out, while argan oil suffuses dry hair with some welcome nourishment. Altogether, this cult favorite keeps your hair looking smooth and shiny, but it’ll genuinely feel stronger, too. This one also works well as a blow-drying primer.

Glowing review: “to say i love this product is an understatement. this is the only product i put in my hair and will not go a day without it. i have gray, curly, coarse hair but it isnt too thick. I put this on my wet hair and then blowdry. I live in a humid climate and if it's just too humid and my hair acts wild i will put some on my dry hair too. it is easy to dispense, smells great and doesnt weigh down my hair. never stop making this product!! it's my one and only.”

Key Ingredients: Keratin-Based Protein Blend, Argan Oil | Size: 1.69 fl. oz.

5. The Best Serum For Heat Styling

If you’re styling your hair with hot tools, you need a serum that provides ample protection from potential heat damage — like this Paul Mitchell Super Skinny Serum. A perennial best-seller, it’s beloved for speeding up blow-drying time and preventing frizz from cropping up in the process. The formula contains lightweight silicones, which are ideal for sealing the cuticle from frizz- and damage-inducing heat and water. Overusing silicones can actually cause limpness and dehydration over time, however, so reserve this heavy-duty serum for your most heat-intensive styling sessions.

Glowing review: “Paul Mitchell Super Skinny Serum is a miracle gel. I was hesitant to spend the money on it but when it arrived I realized it will last for months! Unlike drugstore serums, it is light, non greasy, and smells great. A pump is about the size of a dime, but that is all I need for my shoulder length hair. It prevents my fine hair from frizzing on the ends when I blow dry and lasts for a couple of days [...] So glad I splurged on this miracle product.”

Key Ingredients: Silicones | Size: 5.1 fl. oz.

6. The Best Budget Hair Serum

When in doubt, go for Garnier Fructis’ Sleek & Shine range. Not only are these products incredibly inexpensive, but they’re really, truly effective (the heavenly, tropical-fruit scent doesn’t hurt, either). In particular, the Sleek & Shine serum gets nearly perfect reviews on Amazon. It helps calm frizz without being too heavy, and it works on curly, wavy, and straight hair alike. And a little goes a long way, so the price-per-wear probably evens out to something like $0.0001, according to my inexpert calculations.

Glowing review: “Even though this is an oil, it,does not leave your hair oily. [...] My hair is silky, soft and shiny. I couldn't be happier with the results. So much so, that I subscribed to keep getting the product. If you are on the fence about buying this anti-frizz oil, don't be!! Buy it. My frizz is completely gone!!!”

Key Ingredients: Argan Oil, Apricot Kernel Oil | Size: 5.1 fl. oz.

7. The Best Premium Hair Serum

For a more luxurious choice, try this Shine Serum from Swedish brand SACHAJUAN. A pro favorite, this serum is packed with vitamin B12 (aka panthenol) to nourish and soften your hair, while dimethicone (a type of silicone) forms a smooth, protective coating over each strand to help absorb humidity. It'll help keep your hair looking smooth and shiny all day long, and it smells amazing, too. It’s something of a splurge, but still less expensive than a blowout, which would honestly give you comparable results.

Glowing review: “[...] My hair takes two hours to smooth out and is frizzy again minutes after I do it, just because it is so curly. I have used every product out there, including every shine serum...at least twice. Nothing works to keep the frizz out of my hair. My stylist used this on me and I fell in love with it. It is abslutely ah-mazing! It keeps my hair completely straight...just-left-the-salon smooth all day. I don't know what it is about this product vs all the others I have used, but it is the only thing I use on my hair, and it is an absolute hair miracle. [...] Also, it has a lovely, subtle fragrance.”

Key Ingredients: Dimethicone, Panthenol | Size: 1 fl. oz.
