    Glossarypermeation

    movement of substances through a membrane or porous material

    Permeation refers to the process by which a substance, such as a liquid or gas, passes through a porous material or membrane. In the context of hair and scalp treatments, permeation is crucial for understanding how active ingredients in topical products penetrate the skin and hair follicles to exert their effects. This process is influenced by factors like the molecular size of the substance, the properties of the membrane, and the presence of enhancers that facilitate deeper penetration.
