How to deal with folliculitis after waxing

I brought a body trimmer a few weeks ago, randomly clipped the hair off of one leg to see how it would be.
Was fine until it started to grow back, felt like a baby cacti but that’s the nature of hair, the stuff just keeps growing.
Appreciate the advice unfortunately I lost my GF two years ago and would find it quite hard to clip the hair there hence the waxing, though not permanent, it at least takes a couple of weeks for the hair to start growing through the skin again.
