I get a considerable ammount of ingrown hairs when I shave, with some being quite nasty (very inflamated and sensitive, laser is out of reach for now, I was considering waxing and epilation but still a out of reach now, I mostly want a way to help prevent ingrown hairs from appearing in the first place or making them go away faster
Waxing will only slow the ingrowns you get if you get them that bad. Switching to epilating definitely helped a little for me on my problem area, which is my thighs, but the biggest difference for me was making sure that I started a chemical exfoliation routine. It’s not perfect, but I use a glycolic acid(‘The ordinary’ brand 7% works great for me) exfoliator daily and it reduced the amount of ingrowns I got by like 95%. Also make sure you’re moisturizing as well!
