Sulfate-free Saari Taika liquid soaps!
Sulfates, i.e. SLS (Sodium Lauryl Sulphate, Sodium Laureth Sulphate, etc.) are surfactants that effectively remove fat.
These inexpensive ingredients cause the product to foam strongly, but at the same time they also remove good and protective fats from the skin, which is why many people may experience itching and other symptoms after using products containing sulfates.
