What to Look For

By now, we’re accustomed to seeing shampoo and body wash—even hand soap—labeled as being “sulfate-free.” In fact, the term sulfate-free has become something of a buzzword. Much like words like nontoxic, natural, and organic, it carries a lot of weight and expectations, and might even drive sales up. So, what are sulfates, and are they inherently bad for your skin and hair?

Sulfates are the foaming agents found in traditional shampoos. You know, the ones where you squeeze a big dollop into the palm of your hand, massage it into your hair, and feel that rich, bubbly lather? Those are sulfates at work. “They’re cleansing agents and create lather to help to strip oil and dirt, but may also strip moisture and color out of the hair,” explains Roz Murray, a stylist at Bumble and bumble in New York City. “They can also cause irritation on a sensitive scalp and create a negative charge which can create unnecessary frizz,” she adds.

That’s why people reach for sulfate-free formulas. They’re thought to keep hair color, moisture, and curls preserved more effectively and for longer than shampoos with these foaming agents. Although they might not lather up like you’re used to, know that your hair is still getting clean while looking healthier at the same time.

Below, our picks of the best sulfate-free shampoos.

This one is targeted specifically toward those who color their hair. Sulfates can be too harsh on color and strip it away over time, so you might see a big difference by switching out your normal shampoo for this sulfate-free and color-protecting formula.

All color-treated hair needs extra TLC no matter the texture, but the stakes definitely go up when you have kinky, coily, or tightly curled hair. Not only will the purple tint prevent brassy tones, but the rice water is just what you need to grow your hair stronger. It also has plenty of slip, so you can safely detangle your tresses.

Byrdie's senior editor Hallie Gould swears by this repairing shampoo from Olaplex, filled with ingredients specifically meant to mend color-treated or damaged hair. Another benefit? "It's the only sulfate-free shampoo that I've ever used that has a satisfying lather," she says. She uses it as her normal shampoo in conjunction with the Olaplex Hair Perfector or Olaplex Conditioner.

Key Ingredients

Aloe vera is a naturally derived ingredient known for its soothing and moisturizing properties. The aloe plant's inner gel mucilage (the part that's used in skincare products) is made up of 99.5% water.

This shampoo fortifies your hair from the inside out, giving it the nutrients it needs to better absorb moisture. Infused with pro-vitamin B5 to help reduce breakage, it smooths the cuticle surface and gently cleanses with aloe vera.

Key Ingredients

Seaweed refers to countless species of marine plants and algae that grow in the ocean. They uptake minerals by absorption and active transport from seawater. Because of these processes, some seaweeds have a dense concentration of vitamins, minerals, amino acids, proteins, and lipids, which all pose benefits for the skin.

This sulfate-free shampoo boasts seaweed extract to moisturize and renew dry and damaged hair. The result is hair that's shiny and balanced.

This natural shampoo uses the nutrient-rich rahua nut to repair dull, stressed-out strands and make your hair shiny and bright again. Quinoa, coconut, organic aloe, and organic green tea all work to bring your tired hair back to life. Plus, the palo santo oil smell is ambrosial.

Mielle Organics Babassu Conditioning Shampoo

A shampoo that leaves your hair feeling both moisturized and squeaky clean is hard to find, but this shampoo with organic babassu oil has done the job. It's ultra clarifying to get rid of product buildup, but it also conditions as it cleans to avoid stripping your curls. The results are less frizz and more definition.

The ghost part of this shampoo's name comes from the Moringa seed oil that's found inside. It has a super lightweight moisturizing capability, so it hydrates and softens without weighing hair down. Multiple members of the Byrdie team approve of this pick.

Final Verdict

The L’Oréal EverPure Sulfate-Free Moisture Shampoo (view at Ulta) earns the top spot on our list, effectively cleansing and leaving strands nice and hydrated (and it’s also super affordable, too). And while all sulfate-free shampoos are a great choice for those with colored hair, the dpHUE Color Fresh Shampoo (view at Derm Store) is an especially outstanding pick if you color your strands, specially formulated to safeguard your hue. Similarly, they’re great if you have damaged tresses—the Olaplex No.4 Bond Maintenance Shampoo (view at Sephora) is our go-to in that scenario—or if you have curly hair, we suggest the Mielle Organics Babassu Conditioning Shampoo (view at Mielle Organics).

What to Look For In a Sulfate-Free Shampoo

Free of all sulfates

Make sure, in fact, that it 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 bonus points if the shampoo you pick contains extra hydrating or conditioning ingredients to further up those effects.

FAQ

Why should you use sulfate-free shampoo?

Using a sulfate-free shampoo is a good way to both help retain the natural moisture in your hair, as well as prolong the life of your hair color, says Murray. It’s also a good option for those with an easily-irritated scalp, as sulfates can cause even more dryness and itching.
Can you use sulfate-free shampoo every day?

Definitely, especially because these formulas are designed to retain moisture.
Does sulfate-free shampoo cause buildup?

Your hair may feel different after you start using a sulfate-free shampoo but, according to Murray, it’s not build-up that’s to blame. Because sulfate-free shampoos remove less of the natural oils, your hair will feel different and it can take a few weeks to get used to how your hair feels after washing, she explains.
