What is a key consideration when performing a chemical service on hair?

When performing a chemical service on hair, understanding the hair texture and porosity is crucial because these factors significantly affect how the hair will respond to the chemical process. Hair texture refers to the thickness or diameter of the hair strands, which can greatly influence the way chemicals penetrate and interact with the hair.

Porosity, on the other hand, describes how well the hair can absorb and retain moisture and products. Hair with high porosity tends to absorb chemicals more quickly, which may necessitate adjustments to the timing and application of the service to prevent damage. Conversely, hair with low porosity might require more time and specific products to achieve the desired results as the chemicals might not penetrate as readily.

Considering these characteristics ensures the stylist can tailor the chemical service to achieve the best outcome while minimizing the risk of damage to the hair. This focus on hair health and appropriate treatment is fundamental to providing effective and safe services in a salon setting.
