Final answer:
It takes a few weeks for a tweezed hair to become visible on the skin's surface, as hair grows around 0.3 mm per day during the anagen phase.
Step-by-step explanation:
After being tweezed, a hair's journey to reach the surface of the skin begins anew from the hair follicle. Since hair under normal circumstances grows at a rate of approximately 0.3 mm per day during the anagen phase of hair growth, it can take a few weeks for a new hair to be visible at the skin's surface after tweezing. Considering the average monthly growth rate of about 1.25 cm (half an inch), the visibility of the hair above the skin will depend on individual growth rates and the phase of hair growth the new hair is in.
