Folliculitis is a common skin condition caused by an infection of the hair follicles.

It can cause mild to severe irritation, leading to redness, swelling, pain, and scabs. Folliculitis can be caused by bacteria such as Staphylococcus aureus (staph) or fungus such as Candida albicans, or even due to irritation from shaving, clothing, oils, and dirt. Without proper treatment, folliculitis can lead to serious infections and can even cause permanent scarring.

It is important to know the signs and symptoms of folliculitis so that it can be properly treated. This article will provide information on the causes, diagnosis, and treatment of folliculitis.

What is Folliculitis?

Folliculitis is a condition in which bacteria, fungus, or other irritants enter the skin and cause an infection in the hair follicles. The infection results in redness, swelling, tenderness, and sometimes a rash. The affected area can also have pimple-like bumps with pus, blisters, or scabs.

In some cases, the bumps can become large and painful, or even develop into boils. Boils can be accompanied by fever and can spread to other parts of the body.

What Causes Folliculitis?

Folliculitis can be caused by bacteria or fungus, or even due to irritation from shaving, clothing, oils, and dirt. Bacterial infections are often caused by Staphylococcus aureus (staph) or Pseudomonas aeruginosa. Fungal infections can be caused by Candida albicans or other fungi.

Staph and Pseudomonas bacteria can live in the air, water, and soil, and are spread from person to person by direct contact or through contact with contaminated surfaces, objects, or food. They can also be spread through sharing items such as towels, linens, and clothing.

Candida albicans is usually present on the skin. It can overgrow when there is a change in the environment, such as a skin injury or a change in diet.

Folliculitis can also be caused by sweat, oils, and dirt that block or irritate the hair follicles. This is known as "irritant folliculitis," which is the most common type of folliculitis. It is typically seen in areas that are often sweaty or covered by clothing, such as the armpits, neck, and groin.

Diagnosis and Treatment of Folliculitis

Folliculitis is typically diagnosed based on the appearance of the rash and a physical examination. A biopsy may also be taken to confirm the diagnosis.

The treatment for folliculitis depends on the type and cause. Bacterial folliculitis is treated with antibiotics, either taken orally or applied to the skin. Antifungal creams may be used to treat fungal folliculitis. Irritant folliculitis can be treated with topical anti-inflammatory creams and avoidance of factors that irritate the skin.
