Strip wax is what most people think of when you mention waxing. It’s runny wax that’s applied in a thin layer using a disposable wooden spatula stick. Hair is then immediately removed by rubbing a disposable strip against it and quickly peeling it off. 

Hot wax is typically thicker in the pot and is applied thickly too. Like with strip wax, your therapist uses a disposable wooden spatula stick to apply it. She’ll likely put on what feels like a few layers, and move the stick around in a few directions, and then leave one edge with some extra wax. Over the next minute or so, the wax will harden slightly during which time your therapist will likely apply wax to another area to save time. She will then “pat’ the wax to check how soft or hard it is – waxing it off prematurely will be less effective. Once ready, she will peel away at that corner where she added more wax (for grip purposes) and then wax off the entire piece. So no wax strip involved, you can just directly peel off this wax.
