depending on how strong ur odor tends to be
I think that an average person should put on deodorant at least 1 time a day. I personally put it on 2 times a day.
Bathe every day and use powder and deodorant if you sweat a lot.

I think you should use deodorant and take a shower or bath every morning or every other day.
Deodorant was around in ancient times but modern day deodorant was invented in 1888 by an inventor in Philadelphia, Pennsylvania.
you did not put on deodorant or you did not put on enough.
You smell better!
when you get in the shower use some body wash or soap that smells good then when you get out make shore you have a dry and clean towel and dry yourself off then put on some perfume and deodorant and clean clothes then you will smell good.
Every day.

well, first of all, if you do lots of physical activity, then you just have an excessive amount of sweat building up. then you just wash it with a washcloth in warm water and put on deodorant. I suggest ones that don't block the sweat, because they're bad for you. It also depends on the age. If you are a young teenager, then it might be hormonal. then, just do the same thing but wear deodorant every day.
Shower everyday (or every second day if your lazy) Throw away your clothes that smell gross Don't lift your arms EVAR Use deodorant
