You've probably come across the term "sulfate-free" when shopping for shampoos over the past several years. Sulfates—which are usually listed as sodium lauryl sulfate (SLS) or sodium laureth sulfate (SLES) on an ingredient list—are foaming agents. This is what gives hair washes that lathering effect.
But while a good lather is undeniably luxurious, foam isn't necessary for cleaning your hair. So what's the harm, then? Sulfates can irritate some people's skin and eyes, and for some, it's about protecting brittle or chemically-processed hair.
"Sulfate-free shampoos are recommended when you want to disrupt the surface of the hair as little as possible," hairstylist Kat Savano says. She explains that SLS and SLES contain salt, which can affect keratin treatments and potentially create friction that leads to frizz. "Most other sulfates come from plant sources and are fine to have in a product." According to hair expert Cataanda James, "Sulfate-free shampoo offers a gentler cleanse, ridding the scalp and hair of any debris and product buildup without stripping its natural oils."
We conducted hours of research on the best sulfate-free shampoos on the market, evaluating each formula on key ingredients, benefits targeted, and scent. After considering dozens of different options and consulting with hair-care experts, we landed on the following best in show.
Best Overall
Playa Every Day Shampoo
Doesn't strip hair
Restores hydration
Decent lather
Suitable for all hair types
The packaging isn't easy to navigate
Our number one pick is Playa's Every Day Shampoo. Suitable for all hair types, it calls on the humectant glycerin, coconut-derived surfactants, and kukui seed oil⁶ to gently cleanse your scalp and hair without stripping their natural oils.
A little of the honey-like formula goes a long way. And if you're craving a bit more lather, just add some extra water and gently massage it into your hair to create a luxurious foam. The scent of this sulfate-free shampoo is also incredible—think fresh and floral with notes of sandalwood and musk.

Some of the best SLS-free hair washes are super affordable. Case in point: OGX. This drugstore gem is suitable for all hair types and textures—leaving just about all who use it with glowing, healthy, and beautiful locks after every wash.
After testing the product ourselves, we noticed that the milky, creamy consistency lathers easily on wet hair. And even better, the formula didn't weigh our hair down, nor did it leave a residue post-shower.

What to Look for in a Sulfate-Free Shampoo
Free of all Sulfates
Make sure that your product of choice is totally sulfate-free. Some formulas will be free of common ones like SLS (sodium lauryl sulfate), but you also want to make sure that there aren't any others in the mix.
Hydrating Ingredients
Choosing a sulfate-free shampoo may help preserve your hair’s moisture in and of itself, but it's an added bonus if the shampoo you pick contains extra hydrating or conditioning ingredients (like the Playa Every Day Shampoo formula) .
