Step-by-step explanation:
The infection in the hair follicles caused by bacteria, shaving, or clothing irritation is known as folliculitis. Folliculitis typically presents as itchy, red bumps and pimples that might contain pus. The condition can result from various factors, including sweat, skin ailments, ingrown hairs, tight clothing, or irritation from shaving. The bacterium Pseudomonas aeruginosa is commonly linked to a specific type of folliculitis known as hot tub folliculitis, which thrives in warm and wet environments such as hot tubs. Treatment of folliculitis usually includes maintaining good hygiene and may involve topical antibiotics to address bacterial involvement.
Staphylococcus aureus and Propionibacterium acnes are other bacteria that can cause skin conditions such as acne, where hair follicles become inflamed due to clogged pores with dead skin cells and fats.
