Which of the following is NOT typically considered a factor in pseudofolliculitis barbae?

Pseudofolliculitis barbae, often referred to as "shaving bumps," occurs when hair curls back into the skin, causing inflammation and irritation. Factors that contribute to this condition primarily revolve around how hair behaves after shaving and how the skin responds to that hair.

Genetic factors influence hair texture and curl pattern, which in turn can predispose an individual to develop this condition. Similarly, shaving technique plays a significant role; improper techniques can exacerbate the problem by creating sharper edges on hairs that are more likely to become ingrown. The curl pattern of the hair also directly relates to how it grows back and can make individuals more susceptible to pseudofolliculitis.

In contrast, the age of the individual is not considered a significant factor in the development of pseudofolliculitis barbae. While age can influence skin texture and sensitivity, it does not have the same direct impact on hair growth patterns or the physiological mechanisms that lead to ingrown hairs as the other factors do. Therefore, age is not typically included among the primary contributors to this condition.
