The bumps of folliculitis may become larger and harder if they form keloids or if there is a deep infection that forms boils. Folliculitis is a bacterial infectious skin disease involving hair follicles and their surrounding tissues, mostly caused by Staphylococcus aureus infecting individual hair follicles. The lesions are red follicular papules in the early stages, followed by red, hardened pustules around the periphery, with yellow scabs forming after rupture, and keloidal bumps, which may appear as keloidal hardened nodules, if they occur in the chest or other parts of the body. If the boil is formed by purulent inflammation of the hair follicle deep and surrounding tissues, it starts as a follicular inflammatory papule, and after the inflammation expands, it forms a hard nodule, causing redness, swelling, heat and pain and the formation of punctate pus plugs. When the folliculitis bumps become bigger and harder, you can go to the hospital specialist, follow the doctor’s instructions for treatment, usually pay attention to skin cleanliness, strengthen the immune system and prevent trauma.
