Overview

Folliculitis is primarily caused by a bacterial infection, often from Staphylococcus species, which invades the hair follicles, leading to inflammation. Other potential causes include fungal infections, viral infections, or damage to hair follicles due to friction from clothing or blockage of the follicle.

Symptoms

The main symptoms of folliculitis include:

• Red and inflamed skin
• Formation of boils or pus-filled blisters around the hair follicles
• Itching or burning sensation on the affected skin
• Potential development of a larger swollen bump or mass in more severe cases, known as a furuncle or carbuncle

Diagnosis

Diagnosis of folliculitis is typically based on a clinical examination of the skin. In some cases, a culture of the pus may be taken to identify the specific type of bacteria or fungus causing the infection.

Treatment

Treatment of folliculitis usually involves:

• Topical antibiotics: Applied directly to the skin to treat the infection.
• Oral antibiotics: If the infection is severe or recurrent.
• Antifungal or antiviral medications: If the folliculitis is caused by a fungus or a virus.

Maintaining good personal hygiene and avoiding irritants can also help to prevent folliculitis.
