My 16 year old started using it August 24. She has smelled like armpit for 10 years, at least... and it hasn't changed with any deodorant so far, including this one. Now what? She drives me nuts with it telling me all evening long, every night she smells sweaty. I just sent her to her room, telling her that telling me every 2 minutes doesn't change it. I'm beyond frustrated. HELP!!!
