Which hair removal method results in the longest lasting results?

Waxing is the hair removal method that results in the longest-lasting effects primarily due to the way it removes hair from the root. When waxing is performed, a depilatory wax is applied to the skin, and once it hardens, it is pulled away, taking the hair, including the bulb, out of the follicle. This process disrupts the hair growth cycle, resulting in a longer period before hair regrowth occurs compared to other methods.

In contrast, methods like shaving and depilation (which generally refers to using creams or lotions that dissolve hair at the skin's surface) only cut or dissolve the hair, leaving the follicle intact, so regrowth happens much faster. Threading, while effective for facial hair removal, also primarily removes hair from the follicle but does not provide the same longevity as waxing, which can offer several weeks without noticeable hair growth.
