Folliculitis: Causes, Symptoms, Diagnosis, Treatment, and Prevention

A common skin condition called folliculitis occurs when hair follicles become inflamed or infected. It can affect any part of the body that has hair, such as the face, arms, legs, back, scalp, groin, and buttocks. A folliculitis outbreak can cause red bumps, pus-filled blisters, itching, pain, and scarring. We will discuss folliculitis' causes, symptoms, diagnosis, treatment, and prevention in this blog post.

Causes of Folliculitis

Folliculitis can be caused by various factors that irritate or damage the hair follicles. Some of the most common causes are:

• Folliculitis is most often caused by bacterial infection. Staphylococcus aureus (staph) is usually responsible for folliculitis, but it can enter hair follicles through cuts, scratches, or shaving, which usually lives on the skin. In addition to Pseudomonas aeruginosa (found in hot tubs and pools), Streptococcus pyogenes (found in impetigo), and Propionibacterium acnes (which can cause acne), folliculitis can also occur in these bacteria.

• Folliculitis is also often caused by fungus. Dermatophytes (which can cause ringworm and athlete's foot), Candida albicans (which can cause yeast infections), and Malassezia furfur (which can cause pityrosporum folliculitis) are the most common fungi that cause folliculitis.

• It is less common for folliculitis to be caused by a viral infection. Among the viruses that can cause folliculitis are herpes simplex virus (which can cause cold sores and genital herpes), varicella-zoster virus (which can cause chickenpox and shingles), and molluscum contagiosum virus (which can cause small flesh-colored bumps).

• Irritation can be caused by friction from clothing, shaving, waxing, plucking, or rubbing; exposure to heat, sweat, or chemicals; or trauma to the skin.

• It can also be caused by underlying skin disorders that affect the hair follicles, such as acne, rosacea, or hidradenitis suppurativa.

Symptoms of Folliculitis

The symptoms of folliculitis depend on the type and severity of the condition. Some of the common symptoms are:

• Clusters of small red bumps or pimples around the hair follicles

• Pus-filled blisters that break open and crust over

• Itchy, burning, or tender skin

• Hair loss or thinning in the affected area

• Dark spots or scars on the skin after healing

Some types of folliculitis may have specific symptoms, such as:

• Hot tub rash: This type of folliculitis is caused by exposure to contaminated water in hot tubs, pools, or water slides. It usually appears within 1 to 2 days after exposure and affects areas where the swimsuit holds water against the skin. The rash consists of round, itchy bumps that may later develop into small blisters.

• Razor bumps: This type of folliculitis is caused by ingrown hairs that curl back into the skin after shaving. It mainly affects people with curly hair who shave too close and is most noticeable on the face and neck. The rash consists of red or dark bumps that may be inflamed or infected.

• Carbuncle: This type of folliculitis is caused by a deep infection of multiple hair follicles. It usually occurs on the back of the neck, shoulders, or thighs. It consists of a large, painful lump that contains pus and may drain fluid. It may also cause fever and malaise.

Diagnosis of Folliculitis

Folliculitis is usually diagnosed based on the appearance and history of the skin condition. Ask your doctor about your symptoms, medical history, medications, personal hygiene habits, and exposure to potential causes of folliculitis. As well as examining your skin, your doctor may also take a sample of fluid or tissue from the affected area to test in a laboratory. This can assist in identifying the type and source of infection as well as ruling out other skin diseases.

Treatment of Folliculitis

The treatment of folliculitis depends on the type and severity of the condition. Some of the common treatments are:

• Self-care: For mild cases of folliculitis, you may be able to treat it at home by following these steps:

• Wash the affected area with warm water and mild soap twice a day.

• Apply a warm compress or soak in a warm bath to relieve pain and inflammation.

• Avoid scratching or picking at the bumps or blisters.

• Avoid shaving or waxing until the condition heals.

• Wear loose-fitting clothing made of natural fibers to prevent irritation.

• Change your towels, sheets, and clothing frequently and wash them in hot water.

• Medications: For moderate to severe cases of folliculitis, or if the condition does not improve with self-care, your doctor may prescribe one or more of the following medications:

• Antibiotics: These are used to treat bacterial infections. They may be given as pills, creams, ointments, or injections. You should complete the full course of antibiotics as prescribed by your doctor and avoid skipping doses or stopping early.

• Antifungals: These are used to treat fungal infections. They may be given as pills, creams, ointments, or shampoos. You should follow the instructions on how to use them and how long to use them.

• Antivirals: These are used to treat viral infections. They may be given as pills, creams, ointments, or injections. You should take them as soon as possible after the onset of symptoms and follow the directions on how to use them and how long to use them.

• Anti-inflammatories: These are used to reduce inflammation and pain. They may be given as pills, creams, ointments, or injections. You should use them as directed by your doctor and avoid overusing them or taking them for longer than recommended.

• Steroids: These are used to suppress the immune system and reduce inflammation. They may be given as pills, creams, ointments, or injections. You should use them only under the supervision of your doctor and follow the instructions on how to use them and how long to use them. You should also be aware of the possible side effects and complications of steroids, such as weight gain, mood changes, increased risk of infection, and bone loss.

• Procedures: For severe cases of folliculitis that do not respond to medications, or for cosmetic reasons, your doctor may recommend one or more of the following procedures:

• Drainage: This involves making a small cut in the skin and draining the pus from the infected area. This can help relieve pain and speed up healing. It may be done under local anesthesia in your doctor’s office or under general anesthesia in a hospital.

• Surgery: This involves removing the infected tissue and repairing the skin with stitches or grafts. This can help prevent recurrence and scarring. It may be done under local or general anesthesia in a hospital.

• Laser hair removal: This involves using a laser beam to destroy the hair follicles and prevent hair growth. This can help prevent folliculitis caused by ingrown hairs or shaving. It may require several sessions to achieve permanent results. It may cause temporary side effects such as redness, swelling, pain, and blistering.

Prevention of Folliculitis

The prevention of folliculitis depends on avoiding or reducing the factors that cause it. Some of the common preventive measures are:

• Make sure that your skin is clean and dry by washing it regularly with warm water and mild soap. Avoid sharing personal items such as towels, razors, or brushes. Clean and disinfect any cuts you may have.

• Wear protective clothing and gloves when handling substances that can irritate your skin such as harsh chemicals, detergents, perfumes, or cosmetics. Rinse your skin thoroughly after handling these substances.

• Choose appropriate hair removal methods: Shave, wax, or pluck your hair carefully and gently. Use a clean razor with a sharp blade and shave in the direction of the hair growth. Use a moisturizer after shaving, replace your razor frequently, and disinfect it after each use. Do not shave too close or too frequently. If you wax or pluck your hair, do so only on dry and clean skin. Apply a soothing lotion after waxing or plucking.

• Make sure hot tubs and pools are properly maintained and chlorinated. Shower before and after using them and dry yourself well. Do not use them if you have cuts or wounds.

• Follow your doctor's advice on how to manage any underlying conditions that affect your skin or immune system, such as diabetes, acne, eczema, HIV/AIDS, or cancer. If you have diabetes, take your medications as prescribed and monitor your blood sugar levels.
