Shave
You can take a (disposable) razor blade under your daily shower and update your armpits and legs. It goes fast, the effect is achieved immediately and it is not expensive. If you skip a day, stubble may soon appear. So you have to keep it up to date. Do not use a knife too many times in succession. The scraps of hair that remain in the blades can cause damage to the skin and infections. Instead of blades, you can also use a lady shave or a hair removal cream.
