Glossary Surface Charge

electrical charge accumulated on a material's surface

Surface charge refers to the electrical charge that accumulates on the surface of a material. In the context of hair and biology, surface charge can influence how hair interacts with various substances, such as shampoos and conditioners, and can affect properties like static electricity and frizz. For professionals, understanding surface charge is crucial for developing hair care products that optimize hair health and manageability by controlling these interactions.
