Sulfates are commonly used in many beauty products, such as shampoos and soaps. But why are sulfates used? What exactly are sulfates, and why do we recommend avoiding them? Let’s dive deeper into this topic.
What are sulfates?
Sulfates are widely used in various cleansing products—such as shampoos, soaps, dishwashing liquids, and other cleaning agents. Sulfates are fat-dissolving ingredients that help create a rich lather. In other words, sulfates break down oils and produce foam when, for example, you wash dishes with dish soap. Sulfates effectively remove dirt, grease, and oils, making them a common ingredient in shampoos, soaps, and other cleansers to strip away impurities from the scalp, skin, and hands. The foaming effect also makes application easier.
Sulfates are also found in toothpaste and some hand creams. While they may be beneficial in dishwashing liquids, are they really suitable for use on your skin, scalp, or hair? The short answer is no. Avoiding sulfates is generally a good idea, especially for those with dry, sensitive, or oily skin and scalps.
Are sulfates harmful?
No, sulfates are not considered dangerous. There is no reason to fear them, but there are several compelling reasons to avoid them, especially if you have a dry, sensitive, or oily scalp. As we’ve discussed before, oily hair can sometimes be caused by a dry scalp that overproduces oil to compensate for the dryness. Sulfates may be the culprit behind this issue.
Sulfates are highly drying and, in many cases, irritating. While they are effective at breaking down oils and cleaning, the problem is that they cleanse too aggressively—stripping away not only dirt and excess oil but also the natural oils essential for a healthy scalp and skin. Sulfates cannot distinguish between unwanted dirt and the natural moisture that protects your skin and hair. As a result, your scalp and skin may become dry, irritated, and imbalanced. If you use a shampoo containing sulfates, you might also notice that your hair feels dry and lifeless, as sulfates penetrate hair strands and dry them out from within. This effect is especially noticeable in damaged or brittle hair.
If you have colored hair, avoiding sulfates can also help maintain your color for longer.
Additionally, some studies suggest that sulfates may contribute to hormonal imbalances and hair loss.
What can you use instead of sulfates?
The demand for sulfate-free shampoos and soaps is growing, and many brands are now offering alternatives. All our products, including our sulfate-free Multi Repair Shampoo and Hydrate & Moisture Shampoo, are completely free of sulfates.
There are other, gentler ingredients that can replace sulfates. Traditionally, sulfate-free products do not lather as much as those containing sulfates, but modern formulations have improved significantly.
For example, our shampoos contain ingredients like Cocamidopropyl Betaine, Sodium Lauroyl Methyl Isethionate, Disodium Laureth Sulfosuccinate, and Sodium Lauryl Sulfoacetate (SLSa). These alternatives help cleanse the hair and create a lather without causing dryness or irritation. Some of these ingredients may sound similar to sulfates, but they are entirely different—they are derived from coconut and are far gentler on the skin and scalp.
Do sulfate-free products really cleanse effectively?
Yes! Our sulfate-free shampoos effectively cleanse without stripping the scalp or hair of its natural oils. At first, this might feel different if you’re used to sulfate-based products, but over time, your scalp and hair will adjust, becoming healthier and more balanced. Many people even notice that their hair stays fresher for longer since the scalp no longer overproduces oil in response to dryness.
To get the best results, we recommend shampooing your hair twice—this ensures a thorough cleanse without compromising moisture balance.
How to identify sulfates on ingredient lists
The higher an ingredient appears on the ingredient list, the greater its concentration in the product. Some people may tolerate low amounts of sulfates, while others experience dryness and irritation from products with higher sulfate content.
When checking product labels, look out for these terms:
- Sodium Lauryl Sulfate
- Sodium Laureth Sulfate
- Sodium Lauryl Ether Sulfate
- Ammonium Lauryl Sulfate
- Ammonium Laureth Sulfate
- Sodium Alkyl Sulfate
- SLS (Sodium Lauryl Sulfate)
- SLES (Sodium Laureth Sulfate)
