Frequently Asked Questions
What causes frizzy hair?
Chances are, the roots of your frizziness stem from multiple factors, but one of the biggest culprits is a lack of moisture. In its simplest definition, frizz occurs when the outermost cuticle layer of the hair shaft is misaligned, creating a jagged appearance. What causes this misalignment, according to Seattle-based hairstylist Jen Atkin, is your hair trying to replenish moisture by absorbing it from the air. “So making sure you’re conditioning and masking will help your hair combat that and leave it moisturized without wanting to absorb the moisture outside,” she previously told Allure.
How to reduce frizz
Frizz isn’t permanent, so there are quite a few ways to address frizzy strands. According to Shelly Aguirre, a hairstylist based in Chicago, frizzy hair is often dry, so moisturization is essential. The best shampoos for frizzy hair target dryness and contain “naturally hydrating ingredients that will smooth the hair shaft but not overly weigh the hair down,” New York City-based hairstylist and colorist Paul Labrecque tells Allure.
More specifically, you’ll want to look for hair products that contain natural oils (such as argan and coconut), shea butter, and aloe vera, all of which, per Labrecque, “help to smooth and tame frizz while gently hydrating and cleansing the hair.” Conversely, every hair pro we spoke to advised steering clear of shampoos with sulfates, which can strip your strands of essential oils and dry them out (spoiler alert: It’s a big no-no when it comes to wrangling frizz).

How we test and review products
We always enlist a range of testers for our makeup vertical, but hair-care products and tools are another story. While there are certainly products that can be used across different hair textures, lengths, curl patterns, thicknesses, colors (natural and unnatural), and needs, hair products are often created with specific consumers in mind. Many are created in order to address a concern (dandruff, breakage, brittleness) or to work most effectively for a specific hair type (4C curls, wavy hair, gray hair). You wouldn’t want to pick up a purple shampoo that’s only been reviewed by someone with, say, auburn hair, or a diffuser that’s never been tested by anyone with curls—right?
For our review of the best shampoos for frizzy hair, we enlisted the help of multiple editors, writers, contributors, and hair stylists—who all deal with frizz and would like sleeker results. Testers considered performance across four primary categories: efficacy, texture and experience, fragrance, and packaging.

Our staff and testers
A beauty product is a personal purchase. You might be searching for a face cream to address persistent dryness or a new nail product to add to your Sunday self-care routine; you may simply be browsing around for the latest launches to hit the hair market. No matter what you seek or your individual needs and concerns, Allure wants to ensure that you love anything we recommend in our stories. We believe that having a diverse team of writers and editors—in addition to the wide range of outside testers and industry experts we regularly call upon—is essential to reaching that goal.
After all, can we really say a skin-care product is the “best” for people over 50 if the only testers we’ve solicited opinions from folks who have yet to hit 30? Can we honestly deem a high-end diffuser worthy of your hard-earned cash if it’s never been tested on curls? We’re proud that our staff spans a wide range of ages, skin tones, hair textures, genders, and backgrounds, which means that we are able to fairly assess any beauty product that comes into the beauty closet.
