Shampoo without sulphates, always clean hair without the harsh chemicals

Julie Bollaart

What are sulphates and why are sulphates bad?

Sulphates. What does it do and what exactly are sulphates? You often don't even realise that you are using shampoo or other cosmetics containing sulphates. Sulphates are in almost all normal shampoos. You will only find sulphate-free shampoo from brands that produce shampoos of higher quality.

All about sulphates

Sulphates. They can be dangerous and dry out the scalp. Sulphates also disrupt hair growth. They strip away natural oils and are also bad for the environment. But what are sulphates, why are they so bad for you and what are the alternatives to them?

You know sulphates as the substance that makes your shampoo lather so nicely (foaming agents). One characteristic of sulphates is their cleansing function. For this reason, they are also used in detergents and toothpaste. This is why people find it hard to get used to shampoo without sulphates; these shampoos lather less and are much thicker, giving you the feeling that you are not cleaning your hair properly. Nothing could be further from the truth!

Sulphates, what types are there?

"Sulphates" is an umbrella term for four types of cleansers with ingredients like sodium lauryl sulphate or ammonium lauryl sulphate. The four cleaners are SLS, SLES, ALS AND ALES. SLS is the best known, which is why more and more people are looking for shampoo without SLS.

Why are sulphates bad for your hair?

There are different types of sulphates The difference is in the compound they form. We list some sulphates for you below.

  • Sodium laureth sulphate (SLS) and sodium lauryl sulphate (SLES). These are often used as foaming agents in cosmetics and personal care products.
  • Ammonium laureth sulphate and ammonium lauryl sulphate. These are also used as foaming agents in cosmetics and personal care products.
  • Magnesium sulphate (Epsom salt). This form is often used as a bath salt or laxative.
  • Copper sulphate is often used as a fungicide in agriculture.
  • Zinc sulphate. This form is used as a fungicide and herbicide in agriculture.
  • Sodium carbonate is also known as soda or washing powder. Sodium carbonate is often used as a detergent and buffering agent in cosmetics and personal care products.

The cleansing function of sulphates is fierce for your scalp. Your hair gets clean, but actually too clean. A shampoo with sulphate also cleanses natural oils, also known as sebum or sebum. Sebum keeps the scalp and your hair supple. This natural oil also protects against external influences. Sulphates have an irritating effect on your scalp and can disrupt hair growth.

A by-product of sulphate is dioxane. Researchers suspect that this substance is strongly linked to cancer, but representative evidence has not yet been found for this.

Where are sulphates found?

The ingredients SLS and SLES are most commonly found in personal products and cleaning products such as:

  • Liquid soap
  • Shampoos
  • Washing powders
  • Washing-up liquids
  • Toothpaste
  • Bath bombs

The amount of SLS and SLES in a product depends on the manufacturer. It can vary from small amounts to almost 50 per cent of the product.

Some sulphates occur naturally and are found in water. Together with other salts and minerals, they help improve the taste of drinking water. Others are found in fertilisers, fungicides and pesticides.

How do you know if there are sulphates in your shampoo?

How do you recognise sulphates? Sulphates are known for their foaming effect. A shampoo without sulphates does (almost) not foam. You probably wonder for the first time if the shampoo cleanses enough and does what it is supposed to do. Don't worry, before you know it, you'll be confident and the lack of lather won't matter to you.

Are parabens also harmful?

Parabens are preservatives often found in cosmetics, such as creams, lotions, shampoos and make-up. Parabens help extend the shelf life of these products. Studies show that some parabens can be absorbed into the skin and also into the blood. There are concerns that these can cause breast cancer. There is no confirmed evidence yet that parabens are harmful to health. Nevertheless, many companies are moving towards producing paraben-free cosmetics. Some products use lower concentrations of parabens in their products as a result.

What are sulphates and why are sulphates bad?

What are the best shampoos without sulphates?

You might wonder why manufacturers use sulphates if they are not safe. The answer is simple: sulphates are cheap and they work. An alternative is sodium lauryl sulphur acetate. The English abbreviation is SLSA, but this substance is not a sulphate and is not as dangerous as sulphates. Shampoos containing sodium lauryl sulphur acetate do not dry out the scalp and are water-soluble, so they are not harmful to the environment. It is a more expensive ingredient, so it is only found in better-quality shampoos. Want to buy sulphate-free shampoo? These are our best shampoos without sulphates.
