Treatments for scalp acne include cortisone injections into the acne administered by a dermatologist, regular shampooing, scalp massages, probiotics and oral antibiotics, according to Women's Health. Dry shampoos should not replace regular ones for treatment, as the dry ones do not remove the dirt buildup and may clog pores.
Scalp acne is a painful condition mostly caused when bacteria mixes with a buildup of dead cells and oil on the hair follicles, explains Women's Health. A person who sweats often or has an oily scalp is more susceptible to the infection than another who does not. Scalp acne is harder to treat than facial acne due to the presence of hair.
