TL; DR
The best sulfate-free formula overall is the Pureology Strength Cure Shampoo. It contains strengthening protein, lathers beautifully without being stripping, and leaves all hair types looking and feeling soft. If you're on a budget, you can't go wrong with the OGX Nourishing + Coconut Milk Shampoo.
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 overall results. After considering dozens of options and consulting with hair-care experts, we landed on the following best in show.

It does a nice job of removing oil and build-up without stripping the hair, and it leaves all hair types looking and feeling soft. We're also giving it bonus points for containing keravis, a strengthening protein that can prevent hair breakage.

It’s free of sulfates, as well as silicones, parabens, and phthalates, and made from 96% naturally-derived ingredients. The clean, floral scent is just the icing on the cake.

Some reviewers noted it left their hair dry
Key ingredients: Chelating agents, hydrolyzed keratin, apple cider vinegar | Scent: Rose & citrus | Size: 10 oz. | Cruelty-Free: Yes
As the name suggests, this formula is ideal for deeply cleaning both the hair and scalp, removing excess oil, as well as mineral build-up from hard water.

Best for Keratin-Treated Hair
Kerastase Discipline Smoothing Shampoo
Great for smoothing
Effective for all hair types and textures
Helps fight humidity
Not clean or cruelty-free
Key ingredients: Morpho-keratine complex | Scent: Floral | Size: 8.5 oz. | Cruelty-Free: No
Consider this shampoo a little extra add-on to your in-salon keratin treatment. Yes, it’s sulfate-free and safe for keratin-treated hair, but it’s also smoothing and humidity-fighting in and of itself, further helping to amplify the effects of that in-salon service.

Works for those with scalp dermatitis
Natural coconut and vanilla scents
May feel greasy to some
Key Ingredients: Coconut, vanilla | Scent: Coconut, vanilla | Size: 16.5 oz. | Cruelty-Free: Yes

And—just as the name suggests—this shampoo is great at protecting colored hair.
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.
