Being a beauty editor means you try just about everything that crosses your desk, and for years, I did just that with shampoo.
Because shampoo is shampoo, right?
Nope. It turns out, there's a BIG difference between regular shampoo and sulfate-free shampoo, which I've been using exclusively for almost a year now. (On my face, I've been avoiding sulfates for even longer.)
In this article, you will learn:
- Why sulfate-free shampoos are better for your hair and skin
- What to look for on product labels
- The best sulfate-free shampoos on the market
But first things first...
What Are Sulfates?
Sulfates are detergents—cleaning and foaming agents—that are found in most rinse-off products such as shampoos and skin cleansers.
You'll see them identified on labels as sodium lauryl sulfate, sodium laureth sulfate or ammonium lauryl sulfate. SSometimes, they're referred to as "SLS" and/or "ALS" for short.
Sulfates are considered safe when used briefly, followed by thoroughly rinsing the skin they touched.
Still, for a great many people, even that short contact is too harsh, leading to the following issues.
Sulfates are known skin irritants. As detergents, they remove oil so effectively that they can actually strip your scalp's outermost protective layer. With a compromised barrier function, it's very easy for harmful bacteria to get in and needed moisture to get out. As a result your scalp can develop sensitivity, dryness, redness and itching.
As if the irritation wasn't bad enough, many people also report getting acne on the scalp and around the hairline! I'm not entirely sure of the mechanism here—it could be from bacteria getting in, or from the harshness of the sulfates causing rebound oil production. I've also read that sulfates can leave behind a film on your scalp that clogs your pores (although don't quote me on that).
I think this happened to me recently because within a day of getting my hair washed at the salon, I developed more than a dozen painful pimples on my scalp (and even a few on my neck) that took more than a week to go away. Since they used a regular light shampoo and a vinegar rinse, no conditioner, I suspect sulfates might be to blame (and possibly too-rich conditioning agents as well, although they do always use volumizing shampoos on me). At any rate, I'll be bringing along my own shampoo next time!
Remember we talked about the Mason Pearson brush and how it distributes your natural scalp oils from roots to tips, making your hair look and feel healthy and glossy? Well, that's not happening so much when you use a sulfate-laden shampoo. The SLS gets rid of oil so well that your lengths can end up lacking moisture and shine. This can be especially problematic for those with dry or curly hair, or people prone to tangling, flyaways and split ends. (Dry hair splits faster.)
By the way, ever since I switched to using sulfate-free products (from World), the woman who usually washes my hair at the salon has started commenting that my hair feels better—softer and smoother—and that it looks thicker. Coincidence? I think not!!!
I'm sure you've heard this one before. Sulfates are widely suspected to speed the fading of hair dye, because they are so stripping.
Hair Loss (Maybe)
Finally, some people have pointed the finger at sulfates for contributing to hair loss, thinning and shedding—indirectly, by causing inflammation of the scalp. The jury's still out on that, but I say, it's MUCH better to be safe than sorry. If you're having this problem and alternatives exist, why wouldn't you use them?!
Here's the bottom line. Sulfates are so prevalent in everything for the same reason you see my other least favourite cosmetic ingredient, petroleum, everywhere. They're cheap, cheap, cheap! Sadly, beauty companies don't care about your skin health as much as they care about their profits...
Fortunately, there are a number of very good sulfate-free options on the market now, that work better than ever.
How to Choose a Sulfate-Free Shampoo
Many sulfate-free shampoo ingredients are derived from coconut oil and fruit sugars, and will give you a safe, gentle clean. Below are some names you'll see on labels (GoodGuide is a great place to look up products that contain them!).
- Coco glucoside
- Lauryl glucoside
- Decyl glucoside
- Caprylyl capryl glucoside
- Sodium cocoyl glutamate
- Disodium cocoyl glutamate
- Sodium cocoamphoacetate
- Disodium laureth sulfosuccinate
- Sodium methyl cocoyl taurate
- Sodium methyl oleoyl taurate
- Sodium cocoyl isethionate
- Ammonium cocoyl isethionate
- Sodium lauryl glucose carboxylate
- Sodium lauroyl lactylate
- Cocamidopropyl betaine*
* This seems to be the most common sulfate-free surfactant, however, my understanding is that it's also the most harsh. Best for people with oily hair who don't have sensitivities.
On to my top picks!

Yarok Feed Your Volume Shampoo
Yarok Feed Your Volume Shampoo takes a little more work to coat your scalp, but it's oh-so-heavenly with its mix of fragrant essential oils (just be cautious if you colour, as they may affect fading).

For more options, go check out Sephora's sulfate-free shampoo page. They're the mainstream beauty retailer with the biggest selection of sulfate-free products, offering both bigger brands and some really cool indie lines. You can also refine your sulfate-free search even further to just natural brands and/or fragrance-free brands. LOVE Sephora's selection and search filters!
In case you couldn't tell, I don't think there's any reason NOT to use a sulfate-free shampoo these days. When I first started out as a beauty editor, that certainly wasn't the case—I can remember abandoning my fair share of products that didn't clean well or were just too aggravating to apply.
Now, ingredient technology is so much better, and we don't have to sacrifice at all on performance or texture. Just about the only thing sulfate shampoos have going for them is that they're cheap, but you can even find sulfate-free shampoos at drugstore prices nowadays.
Most importantly, my hair seems in MUCH better condition after going sulfate-free, and apparently my scalp is happier, too. Have you made the switch yet?
