Scalp bumps can appear as small raised spots, tender pimples, itchy follicle bumps, acne-like lesions, or recurring irritation around the hair follicles. They may be linked with scalp folliculitis, product buildup, sweat, oiliness, shaving, clogged follicles, bacterial imbalance, fungal imbalance, seborrheic dermatitis, or skin barrier disruption.
