How to prevent folliculitis and ingrowns after waxing?

Everytime I’ve gotten waxed, I always get really bad folliculitis and some ingrowns. I have a Brazilian booked and I want to minimize the folliculitis as it lasts for weeks and then leaves me with marks. I have only ever waxed my arms and chest. I feel like the folliculitis is worse on finer hair like my upper arms and chest area. This happens when I shave sometimes too.

Are there any products that I can buy to reduce/eliminate this? Or techniques I can try? Does tend skin or bush balm work?
