Sulfur soap is clinically acceptable for washing hair; however, it is not suitable for all people to use sulfur soap to wash their hair. Because sulfur soap is an acidic ingredient, it may cause hair hair damage and scalp damage if it is used frequently to wash hair. Some skin conditions such as seborrheic dermatitis or ringworm are allowed to use sulfur soap to wash their hair. Use sulfur soap to wash your hair as intermittently as possible, not every day, may cause scalp damage, especially hair damage, because this soap is, after all, an oxidizing agent that can cause oxidation and damage to the cuticle of the skin. But for fungal infections, the use of sulfur soap to wash your hair has the effect of curbing the reproduction of fungi and the development of fungal infections.
