Understandably, there's been a lot of talk online recently about how certain popular ingredients lurking in your washday lineup can negatively impact the look, feel, and appearance of your strands over time. It's easy to assume that every shampoo will support the health of your scalp and hair with a nourishing formula, but not all serve the same purpose in a hair journey. We've been seeing more sulfate-free formulas for washday essentials hit the shelves lately, and it's no coincidence! Multiple studies have proven that nixing the ingredient completely from your haircare routine can make a huge difference, but why?
Anyone who haunts the aisles of your local beauty supply store as frequently as I do (or just enjoys discovering haircare essentials online), you've most likely spotted a sulfate-free label proudly displayed on shampoo and conditioner bottles. By taking note of their positive-looking imagery and language used in the designs of their packaging alone, you may have a general understanding of its positive impact using sulfate-free shampoo formulas can have on your strands; the specifics are lesser known to the average consumer. If that sounds like you (which, unless you're a trichologist, is most likely), read on to learn more about these products from experts, and then shop the top product recommendations.
What Are Sulfate-Free Shampoos?
The consensus is that shampoos using formulas without sulfates are better for hair and scalp health, but the facts have to do with how sulfates work. Carrie Prowant, a trichologist, stylist, and Keranique National Platform Artist, breaks down the specifics for us. "Sulfate-free means that there is a group of chemical detergents and surfactants that are not included in the formulation of the shampoo," Prowant begins. "Some of the most common sulfates are sodium lauryl sulfate, sodium laureth sulfate, and ammonium lauryl sulfate." According to Prowant, sulfates create a foam and lather, offering a strong cleansing ingredient that can sweep away oils, dirt, and buildup from the hair and scalp.
As great a sulfates are for removing dirt and grime, they can also inflict some damage. Prowant tells us they cause irritation, inflammation, and dryness by stripping the natural oils your hair and scalp need to thrive, resulting in increased oiliness, dryness of the scalp, and flakiness. Sulfates can also roughen or lift the cuticle layer, strip the hair of color quickly, and weaken the strands, resulting in breakage. "Sulfate-free shampoos are formulated without harsh detergents like sodium lauryl sulfate or sodium laureth sulfate, which can strip the hair and scalp of their natural oils," adds trichologist and scalp specialist Simone Eddie. "They use gentler cleansing agents that help maintain moisture and protect the scalp barrier, making them ideal for dry, curly, or chemically treated hair."
What Should I Look for in a Sulfate-Free Shampoo?
Eddie tells us that searching for an effective, sulfate-free shampoo to add to your washday routine should come down to identifying the ingredients that support the health of your scalp and strands. To do this, she suggests opting for shampoos that use formulas powered by hydrating ingredients like aloe vera, panthenol, and gentle surfactants like sodium cocoyl isethionate or coco-betaine. "These keep the scalp balanced while ensuring a thorough yet non-stripping cleanse," she says. Prowant also suggests checking shampoo for additional gentle cleansers (sodium lauroyl methyl isethionate, decyl glucoside or lauryl glucoside) and helpful natural ingredients.
Peppermint, rosemary, and tea tree oils, for example, are scalp stimulants and antimicrobials while niacinamide and caffeine improve circulation and salicylic acid offers oil balancing and gentle exfoliation. In addition to aloe vera and panthenol, others that prevent breakage and dryness are glycerin, hydrolyzed keratin, and hyaluronic acid. Alternately, harmful ingredients like parabens, isopropyl alcohol, artificial dyes, and synthetic fragrances should be avoided. If you're wondering which sulfate-free shampoos these experts and beauty editors recommend, you're in luck! We're sharing our top picks below, along with reviews from customers who've made the upgrade to their haircare routine.
