Folliculitis is inflammation of the upper portion of hair follicles, causing small, red bumps that may be tender. Sometimes these bumps are topped by a whitehead or pustule. Folliculitis is caused by many factors, including bacterial infection of the follicles, yeast overgrowth, or occlusion of the hair follicles. Exacerbating factors include tight-fitting, non-breathable clothing, high temperatures and humidity, and traumatizing hairy regions by shaving. Some individuals are more prone to folliculitis when shaving than others. There are a few treatments for folliculitis. Avoiding triggers or exacerbating factors is the most important first step. Over the counter and prescription, topical products can also help. In addition, laser hair removal can decrease hair growth in certain areas, thereby decreasing shaving needs and associated folliculitis.
