Painful, itchy bumps on the scalp can be more than simple irritation. They may point to scalp folliculitis, a condition where hair follicles become inflamed due to bacteria, yeast, mites, excess oil, sweat, or clogged pores. These bumps can appear red, tender, pus-filled, and uncomfortable, especially when the scalp stays oily or heavy hair products are used frequently. This video explains what scalp folliculitis may look like, why it develops, and how the right scalp care routine can help reduce flare-ups. A salicylic acid shampoo may support gentle exfoliation and clear clogged follicles, while antimicrobial shampoos with ingredients such as ketoconazole or ciclopirox may help manage bacterial or fungal involvement. Avoiding heavy oils, greasy styling products, and excessive scalp buildup is also important. If symptoms continue, spread, or become painful, a dermatologist may prescribe targeted creams or anti-inflammatory treatment.
