What Are Scalp Infections?

Scalp infections are conditions that affect the skin and hair follicles of the scalp, resulting from the invasion of pathogenic organisms such as fungi, bacteria, viruses, and parasites. These infections can cause a range of symptoms, including itching, redness, scaling, and hair loss, and can affect people of all ages.

Most Common 5 Different Types of Scalp Infections
