Frequently Asked Questions
What causes hair color to fade?
Extra care is a must for your dye job since there are a number of contributing factors when it comes to your color fading. Watch out for exposure to hard water, the overuse of heat-styling tools (and hot shower temperatures), and even UV rays. “The sun bleaches color out of everything, including your hair,” St. Louis-based colorist Caitlin Ford tells Allure. “If you’re going outside for extended periods of time, protect your scalp and hair with a hat,” she adds. We also like to spritz on a little hair sunscreen to make sure we’ve covered all of our bases.
What are sulfates, and are they bad for color-treated hair?
Sulfates are cleansers that trap oil-based dirt so it can be rinsed away from skin or hair with water. They also happen to be the additives behind the lather and bubbles in shampoos, toothpastes, and soaps. Overall, the jury is still kind of out on whether they’re harmful or not, but this group of ingredients is definitely known for its color-stripping effects.
While sulfates are usually given the side-eye—for example, they’re a no-go, according to our very own Clean Best of Beauty seal—they aren’t necessarily as bad for preserving your hair pigment as they’re made out to be. Cosmetic chemist Randy Schueller previously told Allure that water is as damaging as any cleanser. “When your hair gets wet, it swells, the hair shaft opens, and some color leaches out,” says Schueller, who tested sulfates against other surfactants and didn’t see any notable differences in terms of fading color. (This is why many experts suggest washing your hair less often and spritzing dry shampoo to buy you extra time in between.)
However, the case against sulfates is still pretty valid — especially if you want to err on the side of caution. Not only are they irritating to the skin, but they are also capable of “stripping the [scalp] of its natural oils” a little too well, Aanand Geria, MD, a board-certified dermatologist in Rutherford, NJ, previously explained to Allure. In other words: Sulfates are a pretty slippery slope, leading to dryness and flaking.
How is shampoo for colored hair different than “regular” shampoos?
Like many experts, Ferrara is a fan of brands with sulfate-free offerings, as she says they will “extend the shelf life of your hair color and prevent fading.” Los Angeles-based colorist and Redken brand ambassador Matt Rez previously shared that using sulfate-free shampoo will keep hair as hydrated as possible. Adding to the chorus is cosmetic chemist Ron Robinson, who told Allure that sulfates can dry hair out, which can be especially damaging after coloring. They’ll also make your eyes burn if they accidentally slip in, which is a universally unpleasant experience.
All to say: Your best bet, when it comes to preserving your color, is to switch your regular shampoo with one that’s specially formulated for color-treated hair. (Please, no clarifying shampoos.)
Which shampoo is right for my hair color?
We’ll have to dabble in the color wheel theory to answer this question. Basically, complementary colors—or colors that are on opposite sides of the color wheel—neutralize each other. Therefore, you can use tinted shampoos, hair masks, and conditioners to balance brassy tones and dullness. “To counteract yellow hues, you need to use something that has violet in it; to counteract orange tones, you’ll need to use blue hues,” St. Louis, Missouri-based colorist Kristina Cheeseman previously told Allure. For minimizing brassy tones, a purple shampoo for blondes and a blue shampoo for brunettes are always your best bets.

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 certain 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 shampoos for colored hair, we enlisted the help of multiple editors, writers, contributors, and hair colorists—many of whom have or have had color-treated hair. Testers considered performance across four primary categories: efficacy, texture and experience, fragrance, and packaging. For more on what’s involved in our reporting, check out our complete reviews process and methodology page.
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.
