All of the following examples are temporary hair removal services EXCEPT:

Electrolysis is a method of hair removal that is classified as a permanent solution. It works by using an electric current to destroy the hair follicle, which prevents future hair growth. This makes it distinct from methods such as shaving, waxing, and tweezing, all of which only remove hair temporarily. Shaving cuts the hair at the skin's surface, waxing removes hair from the root but allows regrowth, and tweezing pulls individual hairs out from the follicle, resulting in regrowth over time. In contrast, electrolysis effectively leads to permanent hair reduction, making it the only method in the list that does not fit the temporary category.
