What process involves both the hair shaft and root being removed?

The correct choice involves the use of depilatory wax because this method effectively removes both the hair shaft and the root. When waxing, a layer of hot or cold wax is applied to the skin, and once it cools and adheres to the hair, the wax is pulled away from the skin, taking the entire hair (including its root) along with it. This results in a longer-lasting hair removal effect compared to methods that only trim or break the hair at the surface.

In contrast, shaving only cuts the hair at the skin's surface and does not involve the extraction of the root. Other methods such as depilation refer broadly to the removal of hair above the skin but can include processes like shaving or using shaving creams that do not involve root extraction. While electrolysis is a method that removes hair by destroying the root through electrical currents, it does not involve waxing and is not the correct answer in this context.
