To answer your question, it is very dependent on the SP you are seeing. It is best you ask them directly about it. Most of the SPs that I have seen prefer clean shave and then, there are others that were disappointed when I showed up clean shaven.
Few things to consider, some SPs have very sensitive skin and your facial / pubic hair can pierce that skin, exposing them to infection. One thing I will highly recommend is to never show up with a stubble, both up and down, as a courtesy to any provider. They will appreciate that.
