For clean-shaven armpit
Most men like to see hairless armpits. For both men and women who wear sleeveless shirts, it is better to have clean armpits. I workout at gym with mostly sleeveless shirts, so I make it a point to have clean armpits. Believe me, hair there looks ugly.
For women, maintaining clean armpits isnt hard at all. You can buy Veet or Anne French, apply there according to the procedure and, within 10 minutes, it is clean. Unless u have an unusual hair growth rate, it should be enough for the week, you can apply the hair removal cream once a week, during the weekend. Good luck !!!
