Pseudofolliculitis barbae: Razor bumps

Last reviewed

What is pseudofolliculitis barbae?

It is a rash that is the skin’s reaction to ingrown hairs. When curly hairs are shaved, they can curl back and the sharp tip can poke the skin. That causes inflammation and bumps. It is also known as razor bumps.

While it is most common in people of African descent it can affect other ethnic groups.
