infection of the scalp caused by bacteria, fungi, or viruses
A scalp infection is a condition where the skin on the scalp becomes inflamed due to the presence of bacteria, fungi, or viruses. Common symptoms include redness, itching, swelling, and sometimes pus-filled sores. These infections can lead to hair loss if not treated promptly and may require antifungal, antibacterial, or antiviral medications depending on the cause.
