If there is an infection, can a pharmacist detect it and prescribe medication? I am thinking of an ingrown hair or insect bite on the eyebrow arch.

If there is an infection, a pharmacist cannot diagnose or prescribe medication. It is recommended to see a doctor in case of an infection, especially if there is redness, swelling, and pain. Applying warm compresses to the affected area for 10-15 minutes at a time can help improve local circulation. If the redness worsens within 24-48 hours, it is best to seek medical advice.
