Some spots in my head feel like acne. What do I do, since I can't put my acne cream onto my hair and scalp, or can i?

Clindamycin/erythro. There are a couple topical antibiotics used for acne that could also be used on the scalp. The main ones are Clindamycin and erythromycin. The Clindamycin comes as a gel or alcohol-based liquid. Either could be used on the scalp. Products containing benzoyl peroxide would tend to bleach the hair over time.
