Exfoliate your Skin
Another way to treat ingrown hairs is to exfoliate your skin. The process would basically remove the dead skin layers of your skin in order to improve the texture of your skin. Exfoliation also helps to prevent ingrown hairs and it is highly recommended that you exfoliate daily by using a gentle facial scrub that contains active ingredients such as the glycolic acid and the salicylic acid too. Sugar is a great exfoliant also!
