sorry dude
theres really mothing you can do. waxing allows dirt and exfolliated skin cells to get into those pulled hair folicles and then it clogs, forming a blackhead or pimple. then if the hair decided to regrow, then you get an ingrown hair. i have a lot of experiece with different methods of hair removal. i have been researching and also my dermatologist has that there is a new lazer out that will kill hairs that are dark on dark skin. really kinda expeinsive but if it cuts my shaving time in half, its worth it. so all you can do is to take some vit. B-5 and hope that you keep it clean. waxing is the worst, so maybe just put up with shaving.
