The simplest and most effective way to prevent ingrown hairs is to abstain from shaving and allow facial and body hair to grow out as normal. When shaving, there are a few precautions that can be taken to prevent ingrown hairs including proper shaving techniques and preparation of the skin before shaving. When shaving, applying the proper amount of lubrication (in the form of shaving cream, gel, or soap) is important to prevent the hair from being forced underneath the surface of the skin. Also the application of too much force with a razor can contribute to hair that is cut shorter than the surrounding dermis.Using a beard trimmer at the lowest setting (1 mm or 0.5 mm) instead of shaving is an effective alternative.
