The smelly problem

So basically NO MATTER WHAT I DO I am always sweaty after making it to school because I have to walk and I always end up smelling bad because of it. I shower every day I use deodorant I use cologne sometimes and still it’s smells it’s not like horrid but I just smell like sweat for the whole day and I hate it. not to mention no matter how good my hair looks before hand, after I make it to school it’s greasy I have to walk 30 minutes every day and live in Florida what the hell do I do nothing is working
