Final answer:
The primary reason for applying moist heat to the brow area before arching is to open up the pores and soften the hair follicles. Moist heat also helps to relax the skin and muscles, increase blood flow, promote faster healing, reduce inflammation, and create a smoother surface.
Step-by-step explanation:
When the pores are open, it becomes easier to remove the hair from the root, resulting in a cleaner and longer-lasting arch. Moist heat, such as using a warm towel or soak, also helps to relax the skin and muscles, making the process more comfortable.
Moist heat works by increasing blood flow to the area, which brings more oxygen and nutrients to the skin. This promotes faster healing and reduces the chances of inflammation or redness. Additionally, the heat can help to soften any dead skin cells or debris, making it easier to exfoliate and achieve a smoother surface.
In summary, applying moist heat to the brow area before arching helps to open up the pores, soften the hair follicles, relax the skin and muscles, increase blood flow, promote faster healing, reduce inflammation, and create a smoother surface for the arching process.
