Hi April! It took me a couple tries to get the hang of it. One time, I tried shortly after working out and it just dripped right off, so it definitely helps to be somewhat cool and dry! Then you just have to spray it on really thick. I hold the bottle just one or two inches from my skin. I usually sit on the edge of my bath tub and do it that way. Grab a magazine (or my cell phone) and read/surf while I wait...give it about 8 minutes. This has worked really well for me! However I do prefer the Shower Power (lotion) for my underarms, seems to stick a bit better. Hope this helps!
