The truth is that almost 65% of a person’s body odor is caused by sweat and grime that collect in the intimate areas. The underarms are most prone to sweating and unfortunately smelling bad. Add a little friction there and it gets stained too.
If you haven’t been paying a lot of attention to your underarms and are leaving them unshaved for most part, you are inviting trouble for yourself. Hairy underarms tend to sweat more so practice hair removal from your underarms on a daily or regular basis.
