Ringworms are a type of fungal infection. This is a skin condition that can occur anywhere in the body. Ringworms can cause patches of hair loss when you develop on the scalp. The term tinea capitis is used to refer to ringworms occurring in an individual's scalp.

The fungus that causes ringworms penetrates the hair fibers in the affected area, causing the hair to become brittle fibers. The affected hair fibers can break easily, leaving an area of bald skin. Tinea on the scalp or tinea capitis development normally begins as a small grain-like growth that gradually expands in size. This leaves temporary bald patches on the scalp.

There are various types of treatment for ringworm, depending on the type of fungus in question. The most widely used antibiotic to treat ringworm is griseofulvin. Some other drugs used to treat tinea capitis is terbinafine, fluconazole and itraconazole. Some types of this disease are resolved spontaneously and do not require any treatment.

  • Folliculitis

Folliculities refers to inflammation of hair follicles. This condition is characterized by very similar growths acne rings with little inflamed areas surrounding the hair follicle.
