2. Forehead

The primary culprit in this scenario remains consistent: an uptick in oil production on your skin. The root of forehead acne might be your hair.

If your hair tends to be oily, that excess oil can easily find its way onto your forehead and potentially clog up the pores in that area.

Additionally, hair products like pomades, gels, and waxes often contain ingredients like cocoa butter or coconut oil, which can leave your skin even more oilier.
