How can I get my hair to grow out at the same time when waxing?

I get waxed (Brazilian & underarms) every 5 weeks. I rarely have issues with my underarms (probably bc I’ve been getting waxed for about a year now) but with my Brazilian it feels like I’m only hair-free for a few days before it becomes noticeable again.

Idk if this is because my hair growth isn’t all on the same “cycle” or what. But it’s really annoying to pay $80 for a wax and see hair growth just a few days later. My esthetician usually misses hair too, and I have to tweeze it myself.

A big part of the reason I wax is because I have a form of OCD where I obsessively pluck my hairs out when stressed. Before waxing I would spend hours tweezing my bikini line. It was really unhealthy and (luckily) waxing has helped me stop.

Is this an issue where I should find a new esthetician? Or wait longer between waxes?? Help!
