I occasionally have an ingrown hair on my leg or bikini area. It's not an issue on my face since I only get one or two dark hairs there, since I turned middle aged. Then I just pluck them. But it is known by some that exfoliation helps with ingrown hairs. Perhaps every so often use a light exfoliating face wash/scrub. There are many you can find in stores. They even sell electric brushes for use on the face, though I'd likely first just try the exfoliating wash, especially if your facial skin is sensitive.
