There are even special shampoos that do not contain sulfates. We learned from experts whether sulfates are so terrible and how sulfate-free shampoos can help.

What are Sulfate-Free Shampoos?

Sulfate-free shampoos are scalp and hair cleansers free of the most popular surfactant, sulfate. It is believed that they are much softer in effect and are better suited for dry and damaged hair.

What are sulfates? These are salts of sulfuric acid. Not all sulfates have the same properties. For example, calcium sulfate is used to make plastic, ferrous sulfate is a mineral food additive, and it is also used in fertilizers. 

Magnesium sulfate (Epsom salt) is used in bath salt mixtures; sodium Laureth sulfate is known for forming a dense foam when combined with water, pushing out pollution.

He is most often added to shampoos and other detergents so that they foam well. In the description of the ingredients, it can be found as the abbreviation SLES or SLS.

Why did people avoid sulfates, which for many years helped to clean houses, clothes, and themselves? It is believed that in the early 1990s, information about the potential toxicity of this ingredient was misinterpreted, which led to a wave of rejection of the use of products with SLS. 

Indeed, in the description of this substance, you can find a warning about possible skin irritation due to service. It is not recommended to swallow it; if it gets into the eyes, rinse them with running water.

However, the most severe accusation against sulfates is the potential carcinogenicity. In 1998, the American Cancer Society clarified this issue: it turned out that some studies were misinterpreted. Also, sulfates were considered the cause of baldness. Research shows that this is not the case.

The only thing you can blame sulfates for is that they can cause skin irritation. This is the reason for the popularity of sulfate-free shampoos, in which these compounds have been replaced with ingredients of plant origin.

“Sulfates SLS, ALS is used in detergents for dishes, floors, and other surfaces. Less harsh sulfates, such as SLES, are added to shampoos, shower gels, and even some baby shampoos. 

But not everyone knows about the differences between them. From this came the opinion that all sulfates are harmful and there is no difference between dishwashing detergent and shampoo.

When creating sulfate-free shampoos, a substance is used that is synthesized from the fatty acids of coconut oil. Such shampoos can consist entirely of natural ingredients, which is ideal for sensitive scalps. 

However, the biological component of the composition can cause allergic reactions. Also, sulfate-free shampoos are not always suitable for people who use styling products, as they do not wash out the silicone in their composition well.

Sulfate-Free Shampoos and Oily Hair

Peeling when overdrying the skin is often confused with dandruff. If, in the first case, the exclusion of sulfates will help, then with dandruff and seborrheic dermatitis, the sulfate-free shampoo will not do anything. 

How to Use Sulfate-Free Shampoos

The fundamental difference in using a sulfate-free product compared to a regular shampoo is that the first one will need more.
