Underarm hair is a breeding ground for bacteria, especially in the summer. It is important to keep underarms smooth and fresh for the sake of basic hygiene if not for cosmetic reasons.
Shaving: Remember to use a sharp razor. After soaping, shaving and patting dry, sprinkle on some talc. Remember not to deodorize for a couple of hours after shaving, as this will cause severe stinging.
Waxing: Painful, but paying. Avoid waxing underarms at home; you'll probably give up half-way.
Creaming: Gives a slightly smoother finish than shaving and results also last longer.
Bleaching: Not advisable.
Tweezing: Not advisable.
