Hair usually grows back beginning with a short stubble within 24-48 hours after which temporary hair removal method?

The reason shaving is the correct answer lies in the nature of the shaving process itself. When hair is shaved, it is cut at the surface of the skin, which means that the hair follicle is left intact and undamaged beneath the skin. This results in a pointy end on the hair shaft as it begins to grow back, which often appears as a short stubble. Because shaving does not disrupt the hair growth cycle or the follicle, it's common for the hair to start re-appearing within 24 to 48 hours.

In contrast, methods such as waxing, tweezing, and threading involve pulling the hair out from the root, leading to a longer regrowth period before the hair appears again. With these methods, the hair must first grow back through the follicle for a certain length before it can be visible again above the skin. This is why the stubble effect associated with shaving is much quicker compared to the other hair removal techniques.
