Hi Kariann,
Thanks for asking a question. Although I'm not a doctor, and therefore cannot give you medical advice, I do have herpes and love Brazilian waxes so hopefully I can help answer your question.
I assume what you're referring to is the way estheticians us a big melting pot of wax for probably all customers. You are worried that someone with herpes will use the wax before you, and the virus may then be transferred to you (or maybe you're worried about giving it to someone else). I understand the concern, given that a Brazilian wax covers a lot of area very close to mucous membranes, and that sometimes waxing can lead to small open wounds. I personally, don't get waxed when I'm having an outbreak, and I'd be surprised if other people did. Also, the wax that is poured on someone else never gets put back in the pot, it gets thrown away. The only way the herpes would get back in the pot would be through the spatula they use to apply the wax. But I find that the spatula is so coated in wax, it's never touching much of my skin. Finally, I would have a hard time believing that the herpes virus could live in hot wax for long enough to infect someone else. If you've been waxed before you know that it gets hot in there!
I would say getting herpes from the waxing salon is about as probable as getting herpes from a toilet seat. There may be a tiny chance, but it's not enough to obsess about.

Have a good bikini season!
