You can't go to just anyone to get waxed, they have to be exceptionally clean and pay attention to detail. Because if one step is skipped, it can cause a rash or infection.
One of the issues is that waxing rooms are notoriously sticky.
They are covered in wax. The wax gets everywhere.
So if you have a beautiful massage room. Unfortunately, it doesn't make sense to add waxing as a service, because there needs to be a specific room for that because of how messy it can be.
Also, be very careful. There are people who do waxing as a full time job that should NOT be waxing because they're not clean or sanitary.
They reuse items that are supposed to be disposable. They don't prepare the skin properly, they contaminate the wax pot , ect
This can all lead to a rash or an infection.
