Razor bumps

I most recently switched from shaving to waxing because I heard it will prevent/lessen ingrown hairs. I’ve only gone once but my skin down there was so flared up and bumped up I was scared that maybe waxing wasn’t for me either. I exfoliate 3-4 times a week and use witch hazel nothing seems to help but I really want to have a smooth kitty with no hyperpigmentation. What do you ladies do? Please don’t say laser we all know that’s the most expensive alternative
