Actually, we have no way of knowing that for sure, for two reasons:
- Juliette/Eve was not a regular hexenbiest. The way she got her powers was completely unprecedented, so there’s no way to say for certain that the same rules apply for if she lost them.
- The magic stick is brand new to us, and if I had to guess I’d say its use on hexenbiests is also completely unprecedented. So there’s no reason to think that a hexenbiest’s powers being “purged” by it would look the same.
Finally, we do have this tidbit in an interview with David Giuntoli that suggests she is indeed not a hexenbiest anymore:
“Yeah, that stick is to hexenbiests what penicillin is to human beings. It just kind of cures all. The stick looks like it cured Juliette of her mortal wounds, or would-have-been mortal wounds, and in the meantime also kind of cured her of her hexenbiest side effects, I suppose. And we see that with Juliette, and I think that if that moment had happened at any other moment, it would have been a much longer moment, but we were in the process of being ambushed so Nick didn’t have a lot of time to process that. But it’s in the back of Nick’s mind. “

You could still be right. Maybe Juliette is still a hexenbiest, and all it did was break through Eve’s mental block and what Hadrian’s Wall did to her. But if so, all of that woge-ing, convulsing, and de-woge-ing seems a little bit of an odd way to show it.
Either way, it’ll certainly be interesting to see how the team deals with it!
