Will a safety razor prevent ingrown hairs and/or razor burn?

Yes. We get ingrown hairs from shaving as a result of the combination of sharp and dull blades in multi-blade razors. They are designed to cut the hair below skin level, which causes ingrown hairs, while the remaining dull blades rake over our skin, resulting in razor burn. With a single, well-designed blade, the hair is cut at skin level. You still experience a close shave, but your hair regrowth isn't trapped below the skin, risking the potential for discomfort and inflammation.
