Introduction

Folliculitis is a common skin condition that occurs when hair follicles become inflamed. There are different types of folliculitis, with bacterial folliculitis and irritative folliculitis being two of the most common forms. While both conditions can cause discomfort and skin irritation, they have distinct characteristics that differentiate them from each other.

Cause

Bacterial folliculitis is caused by an infection of the hair follicles by bacteria, most commonly Staphylococcus aureus. This type of folliculitis typically occurs when hair follicles are damaged or blocked, allowing bacteria to enter and cause an infection. On the other hand, irritative folliculitis is caused by irritation or damage to the hair follicles from external factors such as friction, shaving, or harsh chemicals in skincare products.

Symptoms

The symptoms of bacterial folliculitis include red, swollen, and pus-filled bumps around hair follicles, which can be itchy and painful. In some cases, the bumps may crust over and form scabs. Irritative folliculitis, on the other hand, presents with red, inflamed bumps that may be tender to the touch. These bumps are typically smaller and do not contain pus.

Diagnosis

Diagnosing bacterial folliculitis usually involves a physical examination of the affected skin and may include a culture of the pus from the bumps to identify the specific bacteria causing the infection. Irritative folliculitis, on the other hand, is often diagnosed based on the appearance of the skin and a review of the patient's skincare routine and habits that may be contributing to the irritation.

Treatment

Treatment for bacterial folliculitis typically involves antibiotics to eliminate the bacterial infection. Topical antibiotics or oral antibiotics may be prescribed depending on the severity of the infection. In contrast, treatment for irritative folliculitis focuses on avoiding the irritants that are causing the inflammation. This may involve changing skincare products, avoiding shaving in certain areas, or using gentle exfoliation techniques.

Prevention

Preventing bacterial folliculitis involves maintaining good hygiene practices, avoiding sharing personal items like towels or razors, and keeping skin clean and dry. Irritative folliculitis can be prevented by using gentle skincare products, avoiding tight clothing that may cause friction, and using proper shaving techniques to reduce irritation to the hair follicles.

Prognosis

Bacterial folliculitis usually responds well to treatment with antibiotics and resolves within a few weeks. However, recurrent infections may occur if proper hygiene practices are not followed. Irritative folliculitis tends to improve with changes in skincare habits and avoiding irritants, but it may recur if the triggers are not identified and avoided.
