Folliculitis is a common infection that affects the hair follicles. The infection commonly occurs due to shaving facial hair. Shaving causes cracks in the skin that allow bacteria to enter the follicles, resulting in bumpy, irritated skin. Hot tub folliculitis can develop when aquatic facilities fail to maintain tubs properly; a bacterium called Pseudomonas aeruginosa, which thrives in hot, poorly chlorinated water, often causes these infections. The best treatment is to keep skin dry and clean; seek a doctor's advice if the issue does not resolve within 72 hours.
