During chemical services, how does hair porosity affect processing time?

When considering the relationship between hair porosity and processing time during chemical services, it's important to understand what porosity means in this context. Porosity refers to the hair's ability to absorb and retain moisture or chemical solutions.

More porous hair has a damaged cuticle, meaning it has gaps and openings that allow chemicals to penetrate more easily and quickly. This leads to a faster processing time because the chemical can act on the hair more effectively. For instance, if you are applying a dye or a relaxer, hair that is more porous will take up the product more rapidly, resulting in less overall processing time needed to achieve the desired effect.

In contrast, hair that is less porous has a more intact cuticle, which may resist the penetration of products. Because of this resistance, these products need more time to effectively work through the hair. Thus, understanding hair porosity can help guide how long to leave a chemical product on to ensure optimal results without over-processing. This connection between porosity and processing time is crucial for achieving the desired outcome in chemical services.
