I don't think she's saying waxing is haram. She is concerned that being waxed in your private area by someone else is haram.
Anyway, I wish I had a solution for this one! It is definitely a pain!
I know i never said waxing is haraam. I said i've waxed b4. Meaning i've waxed some 1 when i was doing my course. And no one told me its haraam. I dont think it is tbh. But if you wanna make life difficult and say it is then go ahead...
