Hi! Unless you have super sweaty hands you don’t need gloves or grip accessories. However, if you’re talking about grip aids to apply to skin well that will depend on what problem you’re having. Do you have dry hands/skin, or sweaty hands/skin?
Before buying grip aids for skin, first make sure you have fully warmed up your body and the pole, sometimes just taking a bit more time to prepare can help.
If you slip because of sweat an antiperspirant like Dry hands powder, Carpe Lotion or Tite Grip II is what you’ll want for hands and body. If you slip because you have dry skin use a sticky or tacky grip aid like, trick tac towel, or my favorite is a mixture of mighty grip and this homemade spray https://www.studioveena.com/videos/view/5e418c06-b198-4d3d-a806-7ffeac110005
