If you're thinking about popping your ingrown hairs, Dr. Mohara warns that popping one of those bumps is a really bad idea. "That just creates more inflammation in the skin and more likelihood of scarring," she says. "If it gets inflamed, go to the dermatologist and get it drained, evaluated for infection, and treated."
To treat an existing ingrown hair, keep your cortisone cream handy to keep it from getting infected. Also, make sure to wear loose-fitting clothing so you don't irritate the bump more.
