Here's Why Experts Say You Should Switch to a Sulfate-Free Shampoo
Sulfate is a common ingredient in beauty products thanks to its sudsing superpowers. Here's why more brands are ditching the additive, and why you should, too.
Maybe your hairstylist has used the term "sulfate-free" when recommending products, or maybe you’ve seen it advertised on more bottles of shampoo lately. To get slightly scientific, sulfate, AKA sodium laureth sulfate, is an ingredient commonly used in hair-care products because of its foaming properties (it's used in other cosmetic and home cleaning items, too). Though the Environmental Working Group's Cosmetics Database says sulfates are safe in small quantities, they can have some not-so-nice side effects like dehydrating strands and stripping color. Here, beauty experts explain why you should switch to a sulfate-free shampoo and share their favorite inexpensive formulas.
What Do Sulfates Do?
“Sulfates are harsh detergents that are commonly found in shampoo and other beauty products. They work by attracting and removing oil from your scalp and hair,” says Hollee Wood, a licensed cosmetologist. “However, they strip the good oils and moisture from your hair, leaving it dry and lifeless.” Over time, using hair products with sulfates can lead to breakage, color fading, and dryness. Even oily strands can be a signal of dry hair; your scalp could be producing more oil to overcompensate for moisture-deprived strands.
So why would companies put sulfate into their shampoos? Well, it is a key ingredient to remove dirt and grease, and it does that effectively—just a little too effectively, making it harsh on your locks. It’s also what gives your shampoo a nice lather. Most of us were taught that a shampoo with a rich lather is the right choice, but that kind of thinking can be wrong, says Shaunda Necole, cosmetologist and beauty blogger.
How to Shop for a Sulfate-Free Shampoo
While most from-the-salon hair products do not include sulfates, it's taken drugstore brands a little longer to hop on the bandwagon. With the trend becoming more popular though, it's getting much easier to find sulfate-free options without calling your stylist. Necole praises the way drugstores have stepped up. "It's so refreshing that these quick-stop beauty shops have leveled up their shelves to include a variety of shampoo brands free of sulfates," she says.
Most package labels clearly indicate when a product like shampoo is sulfate-free; another giveaway is the price tag. “Typically, sulfate-free formulas are more expensive than other options,” says celebrity hairstylist Paul Labrecque. He notes that sodium laureth sulfate is inexpensive and readily available, so it's typically added into formulas right after water.
The benefits you’ll get from spending a little extra on a sulfate-free option are noticeable, especially if you regularly color or highlight your hair. “A sulfate-free formula will provide less stripping of your hair, more moisture retention so your strands won’t be as dry, less color fading and damage, and better scalp health,” says Labrecque. The only thing you might miss about your old shampoo? The big bubbly suds.
