Dear Practo User, Pimples occur on scalp when pores, or hair follicles, get clogged. This can occur when dead skin cells, naturally occurring oil that keeps the skin moisturized (sebum), and bacteria enter the pores. The cells cannot exit the pore, which results in acne in a variety of forms. More severe forms of acne contain more bacteria.
