Final answer:
There are several reasons why you would re-wet the hair during processing, including maintaining moisture, activating chemical reactions, facilitating even processing, and making adjustments.
Step-by-step explanation:
There are several reasons why you would re-wet the hair during processing:
- To maintain moisture: Re-wetting the hair helps to prevent the hair from drying out and becoming brittle during the processing time.
- To activate chemical reactions: Some chemical treatments, such as hair coloring or perming, require moisture to activate the chemicals and achieve the desired result.
- To facilitate even processing: Re-wetting the hair can help distribute the processing product evenly, ensuring that all sections of the hair receive equal treatment.
- To make adjustments: If the initial processing didn't yield the desired outcome, re-wetting the hair allows for adjustments to be made, such as adding more product or extending processing time.
