Why you should never use SLS but SLES is the best!

If you have sensitive skin the chances are you’ll know all about Sodium Lauryl Sulfate (SLS) and how bad it can be for the skin. It used to be an ingredient in all the eczema and dry skin emollients but is now widely known to be a skin irritant. You’ll see so many products labelled as SLS free.

But what about SLES? Many people wrongly assume these two skincare ingredients are the same or at least in some way related but they’re nothing alike. Read on to find out more…

Understanding the Difference: SLS vs. SLES in Haircare

For those who prioritise conscious beauty and have sensitive skin like yours, it’s essential to be familiar with SLS (Sodium Lauryl Sulfate) and SLES (Sodium Laureth Sulfate), two common ingredients found in many beauty products, especially shampoos. While they share similar names, there is a significant distinction between the two.

What is SLS used for in skincare?

SLS, also known as Sodium Lauryl Sulfate or Sodium Dodecyl Sulfate, is widely used as a surfactant in shampoos. Its purpose is to trap oil-based dirt, allowing it to be washed away with water. Additionally, SLS creates the rich lather we associate with cleansing our hair, giving us a satisfying washing experience.

What does SLS do to sensitive skin and scalps?

It is a known irritant and can lead to dry, cracked, and tender skin, which can be particularly problematic for those with sensitive skin or scalp issues like Topical Steroid Withdrawal (TSW), psoriasis and eczema.

Furthermore, shampoos containing SLS have been linked to hair weakening and loss over time. It can linger in hair follicles, gradually weakening them, which is a concern for individuals seeking stronger and healthier hair. If you use a shampoo with SLS make sure to rinse twice to help avoid the effects.

SLES won’t irritate your scalp and skin

In contrast, Olsson’s Allergy UK approved haircare products contain SLES (Sodium Laureth Sulfate), derived from SLS through a process called ethoxylation. This process makes the compound much gentler on the skin and hair. Unlike SLS, SLES won’t irritate the scalp or strip it of essential moisture, providing a more nurturing and nourishing experience, which I can vouch for!

Harnessing the benefits of SLES along with other skin-friendly ingredients like Aloe Vera, Pro Vitamin B5, and Glycerine, Olsson have formulated the ultimate “pure performance” haircare collection. This enables all individuals, including those with skin sensitivities, to achieve clean, shiny, and nourished hair.

ALWAYS patch test any product you use on sensitive skin

As you will know, the complex nature of allergies and sensitivities means that the brand cannot guarantee that their products won’t irritate, but they do offer a free patch test (all you pay is the postage) – which is a great way to find out if the haircare is right for you and SLES is kind enough for your sensitivity.

For any enquiries or concerns, Olsson have a dedicated team of experts, including professional Stylists and Chemists, who are eager to provide support and guidance. So, do ask them – in my experience, if they don’t know the answers, they will find out for you.
