Razor bumps appear when recently shaved hair curls back into the skin causing irritation. Luckily, there are steps you can take to help prevent these annoying bumps. The first is to never shave dry skin. You should always take a hot shower before you shave to open pores. Additionally, use a thick shaving cream or rich conditioner to help keep the hair soft. Always shave your hair in the direction it grows and use as few strokes as possible. Once you are done shaving, rinse the area off with cold water to help close pores and apply a topical, razor bump product.
