Nowadays, many people have been betting on sulfate free shampoo. But do you know why? Dr. Flávia Basilio (CRM: 28624), dermatologist, explains that the cleansing ability of a shampoo depends on the surface activity of its detergent (surfactant). Most shampoos are based on anionic surfactants (sulfates), which are responsible for forming the foam. The most common is sodium lauryl sulfate (SLS), which has a low bioaccumulation profile in the body and is readily biodegradable ?, he says.

However, Dr. Flávia explains, due to the high ability to remove residues and even the natural greasiness of the scalp, sulfates can leave the feeling of dehydrated hair. Learn more about the features of sulfate-free shampoos below.

Sulfate-Free Shampoo X

Dr. Rodrigo Pirmez (CRM: 52.89677-2), dermatologist Member of the Brazilian Society of Dermatology, explains that there are several types of surfactants (substances used in shampoos to promote cleansing). Some have a greater ability to remove tallow and debris from wires such as sulphates. Due to their high cleaning power, sulphates can make hair dry, especially hair with previous treatments and hair that is naturally drier, like curly hair ?, he says.

Considering this, sulfate-free shampoos have emerged. ? They are developed by removing the anionic group, giving rise to the concept? Low poo? ("less shampoo"), which consists of products that use less detergent surfactants. Already the method? No poo? ("No shampoo") is to avoid using shampoos when cleaning hair and scalp and involves different cleaning methods. However, there are no studies that support the hypotheses of the method ?, comments Dr. Flavia.

How to tell if your shampoo has sulfate

It is essential to pay attention to the product label. Dr. Rodrigo points out that in the list of components, assets are usually listed in descending order of predominance. "There are different surfactants containing sulfates, such as sodium laurel sulfate, sodium lauryl ether sulfate and ammonium laureth sulfate," he recalls.

Dr. Flávia warns that completely abolishing shampoo use can lead to other problems such as excessive oiliness, seborrheic dermatitis, dandruff and even infections. Still in this universe, there is the concept of co-wash. This last method is not harmful to the hair. However, the function of a conditioner is very different from the function of a shampoo, being inappropriate with washing substitute.


All this reinforces that the ideal is to make an assessment with a dermatologist, so that the professional can guide the best type of product for your scalp and hair, because the shampoo that is great for one person will not necessarily be good for another.
