Here's How to Treat Pimples on Scalp: Home Remedies Causes, and Prevention

Acne is a very common skin condition caused by excess sebum or oil production by the sebaceous glands present in the skin. It leads to the formation of pimples on the face, upper arms, back, and sometimes on the scalp. Pimples on scalp can be due to two reasons — acne vulgaris and scalp folliculitis.

Acne vulgaris is a condition in which excess sebum and dirt accumulate in pores and cause red bumps on the skin. On the other hand, folliculitis is a condition in which the hair follicles on the scalp get inflamed and lead to pimples on the scalp.
