Which part of the body is most often affected by folliculitis?

Folliculitis primarily affects the bearded areas of the face due to the presence of facial hair and the nature of grooming practices. The hair follicles in these areas are more prone to inflammation and infection, especially when subjected to regular shaving, which can irritate the skin and lead to the blockage of hair follicles. This irritation can create an environment conducive to bacterial or fungal growth, resulting in folliculitis.

While folliculitis can occur on other parts of the body, such as the scalp, back, and arms, the facial hair environment in the bearded areas particularly enhances the likelihood of this condition occurring. These areas are also frequently touched or irritated by products like razors, aftershaves, and other grooming products, further increasing susceptibility to follicular inflammation.
