Why is it important to analyze hair texture before a chemical service?

Analyzing hair texture before a chemical service is crucial because it helps in determining the appropriate treatment that should be applied. Different hair textures, such as fine, medium, or coarse, react differently to chemical treatments like coloring, perming, or relaxing. Knowing the texture allows a cosmetologist to customize the products and processes used to ensure optimal results while minimizing damage to the hair. For example, fine hair may require a gentler formula than coarse hair to avoid over-processing. Understanding hair texture thus directly influences the effectiveness and safety of the chemical service being performed.
