Keeping yourself clean and smelling great is key to your personal wellness in the US. The average American will shower 6 days a week, wash their hair 4-5 times per week, brush their hair and teeth 2 times per day, and floss 4 times per week. 90% of Americans also use deodorant or antiperspirant. The smell of "body odor", or BO, is not socially acceptable in the US. It's important to remain on a schedule with your personal hygiene.
There is a difference between antiperspirant and deodorant, but both work at minimizing under-arm odor. Antiperspirant has active ingredients (aluminum) that prevent sweating in your underarms. Deodorant does not prevent sweating, but works as a fragranced item to limit odor. Apply as often as needed- after showering, in the AM/PM, or when you start to notice an odor. Both antiperspirant and deodorant can be found at local stores (Walmart, Target, CVS, Walgreens). They are available in spray, solid, or gel forms.
