Background

The study of human hair surface is of great interest for the cosmetic science. The hair surface structure is important for the diffusion of compounds, such as cosmetic products

Hair Surface

Polymers are usually used in hair cosmetics for the improvement of the hair surface. They adhere to the hair surface by van der Waals type forces. Several techniques have been proposed for the evaluation of the morphologic changes in the hair surface after treatments with solutions containing polymers. Among the most used ones is AFM.
