The service that requires a thorough knowledge of hair texture and types is perming. When performing a perm, it is essential to understand how different hair types – such as straight, wavy, curly, fine, or coarse – react to the chemicals used in the perm solution and the physical manipulation involved in the process.

Each hair texture behaves differently when subjected to the chemical processes necessary for creating curls or waves. For example, fine hair may not hold a perm as well as coarse hair, which demands an understanding of how to adjust the perm solution's strength and the size of the rods used for rolling. Additionally, recognizing the porosity and elasticity of the hair can impact the final results of the perm, making knowledge of these characteristics vital for achieving desired outcomes.

In contrast, while haircutting, shaving, and hair coloring do require some understanding of hair characteristics, they do not necessitate the extensive chemical knowledge of hair texture and types that perming does.
