Ref. No. 2785/45-4351
In the name of Allah the most Gracious the most Merciful
The answer to your question is as follows:
A Muslim woman is not allowed to get her body waxed by a non- muslim woman. In such cases, she should do it by her own hands as much as possible or seek help from her husband only. She should avoid taking help of strangers in this regard.
And Allah knows best
