4 Ingredients That Look Scary But Are Actually Good For Your Hair

4 Ingredients That Look Scary But Are Actually Good For Your Hair

While we’re all pretty familiar with the benefits of ingredients like aloe vera and argan oil, many of the best (and safest) ingredients for our hair sound a lot less wholesome and a lot more, well, terrifying. And if you read hair product labels, you’ve probably been stumped by a few unrecognizable, scary-looking ones. 

That’s why we’ve decoded four of our favorite ingredients that may sound sinister, but are actually good—and safe!—for your hair. Though they may be tricky to pronounce, they deliver important benefits that help keep your hair healthy and manageable. We like to think of them as the unsung heroes of clean hair care—partially because nobody can sing (or say) their names properly. Read on to learn what they do and why we love them in our products. 


Let the Odele chemistry class begin.

Sodium Lauroyl Methyl Isethionate

function: mild cleanser 

found in: Volumizing Shampoo , Smoothing Shampoo  

EWG Rating: 1

Sodium lauroyl methyl isethionate is a cleansing agent (aka surfactant) that can be found in clarifying shampoos, body washes and even toothpastes. Derived from coconuts, it’s a safe, mild alternative to harsh sulfates and other aggressive surfactants that can strip the hair of its natural oils.

We’ll get this out of the way, too—it’s not the same as sodium lauryl sulfate, which is another common cleansing agent. 

Because clarifying shampoos are designed to remove oil and buildup from the hair, they typically contain surfactants that have oil-attracting properties. When you work the shampoo into your hair and scalp, the surfactant binds to those oils and impurities, removing them from the hair when it’s rinsed out. 

 Our scalp produces a natural oil called sebum. Too much sebum buildup can leave our locks looking dull and greasy, but some is necessary to keep the hair and scalp healthy and moisturized. Sodium lauroyl methyl isethionate helps achieve that balance: it gently cleanses the hair without removing those vital oils, allowing the hair to retain its moisture and shine. Plus, unlike other sulfate alternatives, it produces a dense, creamy lather—so you can still suds up without stripping your strands. (Bonus: it’s biodegradable, so it’s gentle on the environment, too.)

Polyquaternium-10

function: conditions, fights frizz

Polyquaternium-10 is a multitasking ingredient that delivers all kinds of hair-boosting benefits, from taming frizz to improving shine. It’s one of many “polyquats”—lab-made ingredients formed from carbon, hydrogen and nitrogen that are frequently used in hair care products for their conditioning and frizz-fighting effects. 

So how does it work? Scientifically speaking, it all comes down to positive and negative charges. Yep, we’re talking electricity. 

Hair is naturally negatively charged. Damaged hair fibers have a higher negative charge, which causes the layers of the hair cuticle to lift and separate from each other—hello, frizz. 

Polyquats like polyquaternium-10 are beneficial to the hair because they have a positive charge. When applied to the hair, the positively charged polyquat binds to the negatively charged cuticle (opposites attract!) and neutralizes the charge, helping to reduce static and smooth the hair. Polyquaternium-10 also provides the unique benefit of forming a film around the strands to condition and protect from damage. The result? A silkier, smoother, more manageable mane.    

Guar Hydroxypropyltrimonium Chloride

function: detangles, smooths, conditions 

found in: Smoothing Shampoo , Curl-Defining No-Lather Shampoo  

EWG Rating: 1

Guar hydroxy- what? Despite its menacing 12-syllable moniker, this ingredient is safe, non-toxic and plant-derived from guar beans. An excellent conditioning agent, you’ll often find it in shampoos, conditioners and body washes. (And you’ll often find us trying to avoid ever having to say it out loud in Odele product development meetings.)

Similar to polyquaternium-10, it uses its positive charge to neutralize the negative charges that create frizz, tangles and static. Along with its detangling powers, it’s especially effective at smoothing and conditioning the hair without weighing it down. 

 

Cetearyl Alcohol

function: hydrates, moisturizes

found in: Smoothing Conditioner , Volumizing Conditioner , Curl-Defining No-Lather Shampoo , Curl-Defining Conditioner , Leave-In Conditioner

EWG Rating: 1 

Cetearyl alcohol is a commonly misunderstood ingredient that’s a lot safer than it sounds. When most of us think “alcohol,” we think about the box of wine in the fridge (hey, it’s a *nice * box). And next, we think of what are called simple alcohols: thin, watery substances like isopropyl (rubbing) alcohol that sanitize but can have drying or irritating effects.  

Cetearyl alcohol, however, falls into the category of fatty alcohols, which are oily, waxy substances that are non-drying and non-irritating. In fact, they’re so gentle that the FDA even allows them in products labeled “alcohol-free.” 

Cetearyl alcohol is made from two other fatty alcohols, cetyl and stearyl, which are 

found in plants like coconut and palm. It’s used in products as an emulsifier—which basically means it stops the mix of oils and water in your conditioner from separating out into a hot mess. It also works to keep the hair hydrated by trapping in moisture and adds “slip” to conditioners and creams to help them easily spread through and coat your hair. A triple win. 

The Gist

These are a few of our favorites, but there are all kinds of safe, hardworking (and often naturally derived) ingredients in your hair products you may not be aware of. Long-lettered chemicals that sound like they come from outer space aren’t always on the no-no list—in fact, they could turn out to be the best thing for your hair.
