Everyone is different. Some shave, some trim, some wax, some have had laser hair removal. As someone noted above, sex work is work, and we have to put work in to keep our genitals smooth and work-ready.
Waxing or sugaring cannot be done weekly (it's honestly laughable that you guys think hair grows fast enough for that?). Waxing can only be done every three-five weeks, once hair is at least a quarter inch long. It does damage the hair follicle, but it takes YEARS to damage the follicles to the point that none of the hair grows back at all. I've been waxing for 10+ years and my coochie still sprouts lady fur.
Laser hair removal works best on dark hair/pale skin (the contrast is important), and takes thousands of dollars and multiple treatments. Despite its infamy, laser treatments don't fully remove hair -- waxing, shaving, trimming, still need to be done every couple of months.
And for those of you that believe we use Nair on our pubic areas, we do NOT. That is very dangerous. Never ever ever use chemicals like that on such delicate skin.
If you are really invested in knowing, simply ask your provider how they manage their hair removal. There is no one answer.
