Final answer:
If a client has very porous hair, the processing time is typically decreased because porous hair absorbs chemicals faster. Stylists need to adjust the processing time to prevent damage. It's vital to assess hair porosity prior to chemical treatments for optimal results.
Correct option is B
]
Step-by-step explanation:
If a stylist's client has very porous hair, this affects the processing time by decreasing it. Porous hair absorbs moisture, dyes, and other chemicals faster due to its open cuticles, which means that the processing time for coloring or chemical treatments should be shorter to avoid over-processing, which can lead to damage. Professionals must always consider the porosity level of the hair to ensure the best outcome of the treatment.
Porous hair refers to hair with a higher absorption ability because of its raised cuticles. A stylist needs to be aware that highly porous hair is more susceptible to moisture and chemicals penetrating quickly and may often result in faster processing times for treatments. Consequently, the stylist must monitor the processing closely and potentially even adjust formulated solutions for optimal results.
It is essential to conduct a porosity test before a chemical process to determine the correct processing time and protect the hair's integrity. High porosity can be due to previous chemical damage, environmental factors, or natural hair texture, and understanding this characteristic helps deliver a personalised service.
