I Have A Hard Time Preventing Sweaty Armpits

I really love to play sports so it is pretty natural that I then sweat a lot. The only problem with that is I don’t like it. I might be into sports but I am a girl that doesn’t like sweaty arm pits. So I am always looking for some new way to prevent sweaty pits. I have tried all sorts of different deodorants and antiperspirants but there hasn’t really been any that totally do the trick. I am thinking about getting one of those prescribed ones but I am not sure if that will work any better than the over counter ones did.
