Everything You Ever Wanted to Know About Scalp Acne, Including How to Treat It

Palm says the causes are still not entirely understood. Although there are some potential triggers. Those include excessive scalp sweating, the use of some hair products or a history of acne.

"Avoid applying products with excess oil and make sure to wash your scalp regularly," advises Dr. Iris Rubin, board certified dermatologist and founder of SEEN, a line of hair products for acne-prone skin. "Also make sure your hair products are noncomedogenic. It turns out hair care products can leave a residue, or an invisible film on your scalp, which has the potential to clog pores and cause acne or breakouts."
