Which of the following is NOT a method of hair removal?

The correct response is the option that identifies bleaching as not being a method of hair removal. When considering hair removal techniques, various methods physically eliminate hair from the skin, such as electrolysis, waxing, and shaving.

Electrolysis uses an electric current to destroy hair follicles, making it a permanent hair removal method. Waxing involves applying a sticky substance to the hair and then quickly removing it, pulling the hair out from the root, while shaving cuts hair at the skin's surface, effectively removing it for a brief period.

On the other hand, bleaching is a process that involves using chemicals to lighten the color of the hair. It does not remove hair; instead, it alters its appearance to make it less visible. This distinction is why bleaching is not classified as a hair removal method. Understanding these differences is vital when studying esthetic practices and methods.
