Sulfates are synthetic detergents found in many shampoos, soaps, and household cleaners. They create the thick,
foamy lather that most people associate with deep cleansing. These detergents cut through grease and wash away oil,
which is helpful for your dirty dishes and laundry. But are sulfates right for your hair?
At Dr. Squatch, we have strong opinions about sulfates (they’re on our sh*t list). That’s why we made a whole lineup of sulfate-free shampoos with naturally derived ingredients. In this article,
we’ll show you the core sulfate-free shampoo benefits and why men with certain hair types might want to switch.
How Do Sulfates Work?
The two main sulfates you’ll hear about in skin and haircare are sodium lauryl sulfate (SLS) and sodium laureth
sulfate (SLES). These are
powerful surfactants whose molecules have water-loving heads and oil-loving tails. The tails grab onto dirt and oil, while the heads grab
onto water.
At the same time, sulfates reduce water’s surface tension, making its molecules stretchier. When you rub a
sulfate-containing product together between your hands, friction forces air into the stretchy water molecules,
creating bubbles and eventually a foamy lather. This lather traps oils on your skin and hair so they wash away in
your sink or shower.
What Does Sulfate-Free Shampoo Do?
Sulfate-free shampoo cleans your hair using milder, plant-derived surfactants known as glucosides. Human hair
naturally carries a slight negative electrical charge, which increases when it’s dry or damaged. Because of this,
traditional
electrically charged (ionic) sulfates can create static and friction by aggressively clinging to the hair. Glucosides are nonionic, meaning they carry no
electrical charge. This neutral makeup allows them to lift away dirt and oil more gently.
Each of these surfactants come from mixing sugar from corn or wheat with fatty alcohols from coconuts. However, they differ in their texture and foaming
capabilities:
-
Decyl glucoside
has a thin, slippery skin feel but creates a light and fluffy lather. It offers a deep, yet gentle clean.
-
Capryl glucoside
is quite watery and fluid, creating bubbles that quickly disappear. It acts as a solubilizer, meaning it helps
oils to mix into water without separating.
-
Coco-glucoside
is the thickest of the three and creates a dense, creamy foam. It adds hydration as it cleans.
A sulfate-free shampoo may contain one or multiple of these ingredients to achieve a gentle clean. They’re
milder on your hair and skin and less affected by factors like water hardness and pH.
Benefits of Sulfate-Free Shampoo
In addition to being naturally derived and milder, sulfate-free shampoo offers these benefits:
-
Preserved natural oils:
Milder, nonionic detergents produce less foam than their ionic counterparts. This removes dirt and oils less
aggressively, leaving some of the oils your scalp naturally produces to keep your hair healthy.
-
Softer, shinier hair:
Sulfate-free shampoos are
gentler on the cuticle layers that protect your hair strands and keep them looking shiny and hydrated.
-
Longer-lasting hair color:
Because they’re milder, sulfate-free shampoos pull less dye out of your hair with each wash, helping extend the
time between salon visits.
-
Less frizz:
Without an electrical charge to rough up the hair cuticle and cause static, sulfate-free shampoos keep stands
smoothed down.
-
Greener formula:
Glucosides are biodegradable and can be sustainably harvested from renewable sources like sugar or as a
byproduct of
olive oil production.
Is Sulfate-Free Shampoo Better for You?
Most men with normal or oily hair won’t notice much of a difference when switching to a sulfate-free shampoo. They
might feel better about choosing an eco-friendly option or supporting a sustainable brand. But aside from a lighter
lather, their routine won’t change much. For others, though, the difference is more noticeable.
Consider sulfate-free shampoo if you have:
-
Dyed or chemically treated hair:
Milder surfactants don’t aggressively lift the hair cuticle, so they remove less dye from your hair with each
wash.
-
Dry, coarse, or textured hair:
Gentle cleansers leave more of your natural oils intact and cause less static and frizz for these hair types.
-
A limited budget:
Though sulfate-free products are slightly pricier up front, you can potentially save on hair dye and smoothing
products due to the above effects. Plus, they’re often packed with other nourishing ingredients like
shea butter and almond oil, giving you more bang for your buck.
How Do You Know If a Shampoo Is Sulfate-Free?
To know for certain that your shampoo is sulfate-free, read the label, and look for any of these common sulfates:
-
Sodium Lauryl Sulfate (SLS)
-
Sodium Laureth Sulfate (SLES)
-
Ammonium Lauryl Sulfate
-
Ammonium Laureth Sulfate (ALS)
-
Sodium Myreth Sulfate (SMS)
-
TEA-Lauryl Sulfate
You should also check for Sodium C14-16 Olefin Sulfonate. It’s not a sulfate, but it’s a similarly strong
surfactant. Shampoos can include it and still be labeled “sulfate-free.” When in doubt,
check our sh*t list for anything you should look out for.
Feel the Difference With Dr. Squatch’s Shampoo
Thanks for coming to our TED Talk about sulfate-free shampoo benefits. We care a lot about giving men the hygiene
products they deserve, and this is a perfect example. Sulfates are effective cleansers. We formulate without them
because we prefer a gentler lather that leaves more of your natural oils in place.
Not only are our natural shampoos sulfate-free, but we also add in oat protein, jojoba oil, and shea butter — stuff that nourishes your hair and skin. They’re just one more way Dr. Squatch can help you look and smell like a champion while being good stewards to
this planet we call home.
FAQ
Can I Use Sulfate-Free Shampoo Every Day?
Yes, sulfate-free shampoos are safe to use daily.
What are the Downsides of Using Sulfate-Free Shampoo?
Sulfate-free shampoo produces a lighter lather that can take a bit more effort to wash with. That’s why we recommend
grabbing a scalp scrubber if you need an extra hand.
It also doesn’t clean as deeply as shampoo with sulfates, but that’s more of a benefit than a downside. “Cleaning
deeply” also means stripping out all the oils from your hair, which can leave it dry and unprotected. As long as you
keep up your
regular grooming habits, sulfate-free shampoos support your hair’s health with a gentler clean that’s less likely to cause
irritation.
