How many times has foam fallen into our eyes when showering and caused us to sting? That itchiness is due to sulphates, one of the main ingredients in most of the shampoos and cosmetics that exist on the market and that are used practically every day. Society has been using them for decades, but that do not contain sulphates or other substances, such as parabens or silicones.
The sulphates are salts originating in sulphuric acid having a high cleaning power and are present in most cleaning products. They are responsible for the foam that the shampoo generates. When it comes to washing hair, they are very effective, although they are also very aggressive components. They are neither toxic nor dangerous, but the truth is that their cleansing action is so strong that it carries both dirt from the hair and its essential oils, which can leave it dry and irritate the scalp.
