irregularities on a material's surface affecting its texture
Surface Roughness, also known as Surface Texture, refers to the irregularities and deviations on the surface of a material. It is typically measured in micrometers (µm) and can affect how a surface interacts with its environment, including factors like friction, adhesion, and wear. For example, in the context of hair, surface roughness can influence how light reflects off the hair, impacting its shine and smoothness.
