How to Get Rid of Scalp Acne Home » How To » How to Get Rid of Scalp Acne Acne can occur on the scalp just like it appears on the face and other parts of the body. This annoying problem can bother many people, both old and young. Just like the rest of the body, the scalp has pores that secrete oil (sebum) to the surface of the scalp. When the bacteria already on the scalp combine with dead skin cells and sebum, the pores get blocked, leading to an outbreak of acne. Several factors contribute to scalp acne, such as hormonal changes (especially during adolescence and at times of menstruation), an unhealthy diet, an allergic reaction, poor hygiene, living in humid conditions, pollution, exposure to certain chemicals and oils, and mechanical factors like wearing tight headgear or habitually scratching your scalp.
