According to a Wella survey, 92 percent of women have dyed their hair at some point in their lives. So when that gorgeous, gleaming color suddenly turns a weird shade of who-knows-what or gets crazy dull a few weeks (or days) later, know you’re not alone. Others have suffered the same fate. But could the right shampoo have saved you from washing that amazing color down the drain or are those color-treated formulas just marketing hype? Here’s what you need to know about caring for colored strands.

The argument FOR sulfate-free shampoos

Most classic shampoos contain detergents that make up around 15 percent of each bottle. Their job: to sweep away dirt and oils that leave strands squeaky clean (most commonly sodium- or ammonium lauryl sulfate and sodium- or ammonium lauryl ether sulfate). However these same detergents can strip the color molecules from the hair cuticle, as well. Conversely, the kinds of cleansing agents dropped into color-treated and sulfate-free formulas typically contain gentler dirt busters that won’t strip hair of color.

Here’s where it gets tricky: There’s not really any scientific proof that going lighter on the suds’ strength makes any difference to hair color preservation. “Shampoos for color-treated hair tend to be sulfate-free but there are no published studies that validate the theory that sulfates fade hair color faster than other surfactants or detergents,” says Ni’Kita Wilson, YouBeauty’s Cosmetic Chemistry Expert.

But there’s no lack of anecdotal evidence. Kyle White, lead colorist at Oscar Blandi in New York City says he can instantly tell the difference between clients who follow his strict healthy hair checklist and those who don’t (plus, abiding acolytes come in way less frequently, which is a dead giveaway they work, he says). “Color-safe products don’t contain alcohol, have low sulfate levels and often contain extra moisturizing elements, emollients and proteins to smooth the cuticle, giving hair luster and shine,” he says.

So does that mean you have to use a shampoo for color-treated locks? Not necessarily. If you think you’d get more benefit from a volumizing, moisturizing, curl-defining or dandruff formula, then go ahead and grab one—just look for one without sulfates to be on the safe side.Some of the best sulfate-free surfactants to look for on the label: sodium lauryl methyl isethionate, ammonium cocyl isethionate, cocamidopropyl hydroxysultaine, decyl glucoside, cocamidopropylamine oxide, sodium lauryl sarcosinate, and sodium lauryl sulfoacetate. “These are mild, yet effective cleansers which provide a luxurious foam that quickly and cleanly rinses out,” says Jim Markham, color veteran and CEO and Founder of ColorProof, and the brains behind cult-favorite Pureology.

QUIZ: Assess Your Hair Condition

Go easy on the heat—indoors and out 

Put. Down. The. Hair. Dryer. “Heat is the biggest factor in color fading,” says Nancy Braun, celebrity colorist at Rossano Ferretti Hair Spa in Beverly Hills and a L’Oréal Professionnel Ambassador. “Flat irons, curling irons and blow dryers all scorch hair and open the cuticle, allowing for dyes to slip out.”“Studies show that having a UV filter in a hair care product can reduce color fading by up to 40 percent,” says Wilson, who adds that most of these findings are based on controlled studies that only reflected washing—not the normal wear and tear that we put our hair through on a daily basis.
