More than likely, these are ingrown hairs. These are thin hairs that cannot push through the skin resulting in inflammation. They can often be painful. The best way to prevent these is by exfoliating frequently using a loofah, exfoliating scrub, or exfoliating glove. We also recommend using an ingrown hair solution (we love tendskin!) and avoiding standing water (baths, swimming pools, hot tubs) for at least 24 hours after your wax. Keep the area that was waxed clean to aid in minimizing ingrown hairs.
