Hairy underarms look less than lovely when you're wearing a tank top or swimsuit. Additionally, bare underarms are more hygienic and less prone to odor on a hot day, but shaving that curvy, concave area smoothly presents a challenge. You can use a disposable razor or an electric razor -- either way, be sure the blades are clean and sharp to prevent painful nicks and cuts. Most important, take your time and use caution to prevent accidental slips.
Wash your underarms to remove antiperspirant or deodorant. Apply a thick, even layer of shaving lotion or gel.
Raise your arm, and then bend your elbow and touch the back of your head or neck to smooth and expose your underarm area.
Shave your armpit gently, moving the razor downward from the top of your underarm. Then move the razor in the opposite direction -- from the bottom of your armpit to the top. Move the razor gently and don't press hard.
Rinse the gel or lotion off with lukewarm water. Dry your armpit by patting it with a soft towel.
