The 8 Best Smoothing Serums For Frizzy Hair

by Lisa Fogarty

There was a time not long ago when those of us with any hair type that had a habit of frizzing up under the right circumstances would resign ourselves to throwing our hair in a bun or ponytail. But, thanks to these amazing smoothing serums for frizzy hair, there are alternatives to the updo when frizzy days happen. The truth is, frizz rarely discriminates when it comes to hair type. And one of the biggest reasons why frizzy hair happens is a lack of moisture — a result of shampooing too much, using heating tools, not conditioning hair enough, and even spending a lot of time in the humid great outdoors.

But, thankfully, hair products have come a long way in recent years and some of the best frizz-fighting serums contain ingredients like essential oils and plant extracts that are known for sealing the cuticle of hair and making it look glossy (coconut and macadamia nut oils are just two of several examples). There are also hair serums available for a multitude of hair types because, as most of us learned when experimenting with products as teenagers, what works on thick, course hair is only going to drag fine locks to the ground — and lightweight serums for thin hair usually don't contain the ingredients needed to hydrate thick hair.

These eight incredible smoothing serums bring shine back to frizzy hair of any texture.


A Coconut Oil-Based Serum Safe For Chemically Treated Hair

Sexy Hair Smooth Frizz Eliminator, $12, Amazon

This hair serum is infused with the goodness of coconut oil and vitamins E and K and is totally safe to use on chemically straightened hair and even extensions. Reviewers with damaged hair say this serum is "weightless," gives lifeless hair more body and shine, and — as promised — goes a long way in helping to combat frizz.


A Leave-In Argan Oil Serum For Course Hair & All Hair Types That Prevents Breakage

Moroccanoil Oil Treatment, $32, Amazon

This highly rated leave-in argan oil hair treatment hydrates and treats dry scalps and hair, thereby preventing frizz. No matter what your hair type and regardless of whether it's chemically damaged, over-processed, or aging, this incredible popular, rich Moroccan argan oil protects it from heat damage and even UV rays, while controlling frizz and infusing it with major shine.


A Humidity-Resistant Serum For Curly Or Wavy Hair Types

Bed Head Control Freak Serum, $9, Amazon

If you have curly or wavy hair, this frizz control and straightening serum from Bed Head can be applied before styling to create smooth, frizz-free locks and help you achieve the perfect blowout. Reviewers say it's never sticky or greasy and makes hair look super shiny.


A Non-Greasy Smoothing Serum For Fine Hair

Herstyler Argan Oil Hair Serum, $9, Amazon

Argan oil is fantastic because it's lightweight but totally effective at softening hair and removing frizz — and it's the key ingredient in this hair serum, which works for dry, brittle, damaged, and color-treated hair. Because of its lightweight formula, it won't weigh down fine or thin hair (but always start with the smallest amount of product possible). Unlike a lot of heavier serums, it can be used everyday after your shampoo to help prevent frizz and keep hair hydrated and conditioned.


A Super Strength Serum That Defines Curls

Zero Frizz Hair Serum, $11, Amazon

If you want a no-frizz hair serum that respects your curls, but helps to improve their texture and shine, this is the one to beat. Reviewers describe this as a super-strength formula (best for medium to thick hair types) and one that turns dry, frizzy hair in to "soft and shiny" hair and never, ever leaves locks "crunchy" like some gels and mousses.


A Weightless Argan Oil Treatment For Any Hair Type

MAK "Ladi" Argan Oil Treatment, $17, Amazon

Even if you mess up and apply a little too much of this argan oil hair serum, reviewers say you'll still wind up with frizz-free hair that retains body and isn't weighed down by these amazing ingredients. This serum contains no alcohol, is perfect for dry and color-treated hair, and won't create built-up or an oily residue on your scalp. Reviewers say it can fix split ends and that a little goes a long way.


A Hemp Oil Serum That Cuts Drying Time In Half

Marrakech Oil Hair Styling Elixir, $23, Amazon

By combining two effective oils — hemp and argan — this hair styling elixir fights frizz, improves hair texture and manageability, adds shine, and can even reduce the time it takes to dry hair by half. It hasn't been tested on animals and is totally free of parabens, gluten, alcohols, dyes, and animal ingredients — and is safe for color-treated hair. Reviewers say a tiny amount of this product, applied before styling, makes hair look "smooth, shiny, and light."


A Cruelty & Artificial Fragrance-Free Treatment

Beauty Without Cruelty Revitalize Leave-In Conditioner, $9, Amazon

This cruelty-free smoothing leave-in conditioner is free of parabens and artificial fragrance. It does contain an amazing blend of coconut oil, aloe vera, soy protein, and biotin for shiny, healthy hair. Reviewers say this product is "not heavy and leaves... hair feeling and looking GREAT!"
