Before you go for the expensive stuff, run over to walmart and get some corn huskers lotion. Smera that all over your body. That will help you stick to the pole with your body. If your hands are sweating, spray some distilled white vinegar on them (cleaning isle), that sometimes helps decrease the sweating for some girls. If your hands need some extra grip, an instructor recomended "heel to toe peppermint sloughing lotion" for my hands. I tried it when I was trying her stainless steel star stand alone and it was cold and super slippery. It totally helped with my hand grip (it is counterintuitive that a lotion would help with grip, but it WORKED!)

Also, you MUST lotion every night. Hydrated skin grips better. Get some "Vaseline total moisture conditioning" lotion and put it on after you shower. You can even pole after putting it on, just let it dry. My skin grips so much better since I started using it! It's glycerine based. It is really awesome. Walmart has a sampler bottle for less than a dollar that you can try.
