Folliculitis

Folliculitis

Also known as Barber’s itch, fungal acne.

Overview


Folliculitis is a skin condition characterized by the inflammation of hair follicles. It occurs when these small, sac-like structures, which house hair roots, become infected or irritated. 

The symptoms typically include red, inflamed bumps or pustules (pus-filled blisters) around hair follicles, often accompanied by itching and pain. Factors that increase the risk of developing folliculitis include excessive sweating, tight clothing, shaving, using hot tubs or whirlpools, and having a weak immune system. 

Treatment typically involves self-care measures such as warm compresses, proper hygiene, and avoiding irritants. In more severe cases, antibiotics or antifungal medications may be prescribed.

Symptoms Of Folliculitis 

 

Here are some common signs and symptoms. They can vary depending on the severity and the underlying cause.

  • Cluster of tiny, painful red bumps around hair follicles.

  • Pus-filled blisters around hair that bleed and crust over.

  • Rashes

  • Itching, burning or painful sensation in the skin

  • Bleeding and crust formation

  • Growth of stiff hair into the skin

Causes Of Folliculitis

 

Folliculitis frequently arises in moist or sweaty areas and can result from infection (bacterial, viral, or fungal) or irritation due to environmental factors and specific skin conditions. Various causes of folliculitis include:


I. Infections

1. Bacteria

  • Superficial bacterial folliculitis is the most common type of bacterial folliculitis caused by the bacteria, Staphylococcus aureus. It usually presents as pustules without fever or other associated symptoms.
  • Hot tub folliculitis is caused by a bacteria called Pseudomonas aeruginosa, found in contaminated water sources like hot tubs, whirlpools or spas.

  • Gram negative folliculitis is a rare facial eruption, usually seen after antibiotic treatment of acne.

2. Fungi

  • Malassezia folliculitis, often called "fungal acne," in layman terms, is a skin condition caused by an overgrowth of the yeast Malassezia in hair follicles. It results in acne-like pustules and red bumps, often on the chest, back, and face.

    Remember!
    Do not confuse fungal acne with common acne (acne vulgaris).
    Common acne results from blocked follicles due to oil, bacteria, and dead skin, while fungal acne is a yeast-driven infection in follicles.
    Fungal acne can be itchy, while typical acne is not.

  • Tinea capitis or scalp ringworm is a fungal infection involving the hair follicles of the scalp. It is usually associated with scaling and hair loss.

3. Virus

Certain viral infections, such as herpes simplex virus or varicella-zoster virus, can cause folliculitis. It mostly affects men who experience recurrent localized facial herpes simplex infections and shave with a razor.

4. Parasite

Demodex folliculitis is caused by the mite demodex. It occurs on the faces of people whose immune system has been suppressed with medications.


II. Environmental Factors

1. Mechanical Folliculitis

Also known as Barber's itch, it results from continuous friction and is often seen in people, who shave their faces or legs with a razor, especially against the hair growth direction.

It can also occasionally be associated with tight clothing or obesity.

Interesting Fact!

Barber's itch is commonly confused with razor bumps. Razor bumps are inflamed, ingrown hairs due to shaving, occurring anywhere on the body, while barber's itch is a fungal infection of hair follicles.

2. Occlusion Folliculitis

It occurs when skin products like heavy oils, moisturizers, or ointments clog hair follicles, leading to swelling and inflammation.

3. Chemical Folliculitis

It occurs when certain topical products, such as coal tars and the overuse of medications like corticosteroids, lead to swelling and blockage of the hair follicle opening, particularly on the face.


III. Other Forms

1. Buttock Folliculitis: This common issue affects both men and women, resembling localized acne.

2. Drug-Induced Folliculitis: This type of folliculitis typically arises within two weeks of taking specific medications, such as oral corticosteroids, androgenic hormones, lithium, and certain other anticonvulsants.

3. Pseudofolliculitis Barbae: It's a chronic inflammation affecting the beard area in men who shave, particularly those with darker skin tones and tightly curled hair. The sharp tips of newly grown, curly hair can penetrate the skin, leading to mechanical inflammation.

4. Irritant Folliculitis: It is observed on the lower legs of women who employ methods like shaving, waxing, plucking, or electrolysis for hair removal.

5. Eosinophilic Folliculitis: This type results in severe itching and recurrent lumps and pimples near hair follicles on the face and upper body. It primarily affects individuals living with HIV/AIDS.

Did you know the difference between acne and folliculitis?
Acne and folliculitis are common skin conditions that can cause similar symptoms, but they have different underlying causes. Acne is a chronic inflammatory condition caused by the overproduction of oil, clogged pores, and bacteria. It usually appears as red bumps or pimples on the face, chest, and back. Whereas, folliculitis is an infection or inflammation of hair follicles caused by bacteria or fungi. It typically presents as small red bumps with a white center around hair follicles. Understanding the difference between acne and folliculitis can help in determining appropriate treatment options for each condition.

Diagnosis Of Folliculitis


The diagnosis of folliculitis usually involves the following possible diagnostic steps:

1. Medical history

  • Your doctor will ask you questions about your symptoms, their duration, and any factors that may contribute to the condition. 

  • They may inquire about your recent exposure to hot tubs, swimming pools, or other potential sources of bacteria or fungi. 

  • The doctor may also ask if you have any medical conditions, use of immunosuppressive medications, or recent antibiotics.

2. Physical examination

  • The doctor will examine the affected area of your skin. They may look for signs such as redness, pustules (small pus-filled bumps), or crusts. 

  • The examination will help differentiate folliculitis from other skin conditions with similar symptoms.

3. Tests

In more severe situations, your doctor may request additional tests to ensure that your folliculitis is not caused by another medical issue, such as:

  • Culture test: A sample of the affected skin may be collected for laboratory testing to identify the specific bacteria or fungi causing the infection.

  • Skin biopsy: In rare cases, a small sample of the affected skin may be taken for microscopic examination to rule out other skin disorders.

Prevention Of Folliculitis


1. Focus on hygiene

Cleanse your skin regularly with mild soap, focusing on folliculitis-prone areas like the scalp, face, neck, armpits, and groin. Keep your skin dry and change out of wet clothes promptly.


2. Choose loose clothing

When it's hot and humid, frequent irritation from tight clothing might cause folliculitis by injuring your hair follicles. Choose clothing that is loose-fitting and allows your skin to breathe.


During hot and humid conditions, heavy sweating can increase the possibilities of fungal infections.

Here are a few tips to help you deal with fungal infections this summer.


3. Don't share personal care items

Avoid sharing towels, razors, or other personal items that come into contact with your skin. This helps prevent the spread of bacteria or fungi that can cause folliculitis.


4. Adopt proper shaving techniques

If you shave, make sure to use a clean razor and shave in the direction of hair growth to reduce the risk of irritation and ingrown hairs. Avoid dry shaving, as it can cause more friction and increase the likelihood of folliculitis.

5. Use sanitized hot tubs

This helps prevent bacterial folliculitis by reducing the risk of infection from contaminated water.


6. Be cautious in public places

Public places can harbor bacteria or fungi that may cause folliculitis. Consider wearing flip-flops or sandals in these areas.


Protect yourself from infections by maintaining adequate hand hygiene. Browse Handwashes And Sanitizers


7. Avoid using harsh chemicals

Chemicals, oils, or greasy skin products can clog the hair follicles and lead to inflammation. Look for non-comedogenic or oil-free products instead.

8. Maintain a healthy immune system

A strong immune system can help prevent infections, including those that cause folliculitis. Maintain a balanced diet, exercise regularly, get enough sleep, and manage stress to support your immune system.

Doctor To Visit


Folliculitis symptoms can range from moderate to severe. Doctors who can help in the diagnosis and treatment of folliculitis are:

  • General physician

  • Dermatologist


A general physician can diagnose folliculitis, often through prescription of antibiotics or topical treatments. A dermatologist (skin specialist) can provide specialized diagnosis and treatment, tailored to the specific type and severity of the condition.


When to see a doctor?

Please contact your doctor if you suffer any of the following:

  • The symptoms worsen or don't improve within a few days of self-care measures

  • The affected area becomes increasingly painful, swollen, or red

  • You develop a fever along with folliculitis

  • The condition spreads to other parts of your body

  • You have a weakened immune system due to a medical condition or certain medication

  • You experience recurring episodes of folliculitis.


Don’t take folliculitis lightly. Seek professional guidance if symptoms persist.

Treatment Of Folliculitis


The treatment of folliculitis depends on the type of folliculitis and its severity. In many cases, mild folliculitis resolves on its own without specific treatment. However, the management of folliculitis include:

1. Treatment of mild to moderate cases

  • Use antibacterial cleansers to gently cleanse affected areas, reducing skin bacteria.

  • Apply antiseptic washes like triclosan 1% or chlorhexidine 2% in showers to curb excess skin bacteria and aid skin health, especially in inflamed hair follicles.

  • Try anti-itch creams.

  • Avoid shaving the affected area until the condition improves

  • Avoid wearing tight clothing or bandages that may irritate the affected area

  • Apply warm compresses to help soothe and reduce inflammation.


2. Treatment of severe cases

Medications based on what is causing folliculitis

  • Eosinophilic folliculitis: Antiretroviral therapy (ART), topical corticosteroids, antihistamines, phototherapy (the skin is exposed to UVA and UVB waves), itraconazole, or isotretinoin. Are generally considered.

For more severe or recurrent cases of folliculitis, there are additional options to consider:


  • Incision and drainage: If a sizable and painful abscess or boil forms,your doctor may opt for a minor surgical procedure to drain the pus and alleviate pressure.


  • Laser hair removal: In cases of recurrent or chronic folliculitis, laser hair removal can be considered. This treatment aims to permanently eliminate the affected hair follicles, reducing the chances of future flare-ups.

Home-care For Folliculitis

 

While home remedies can provide temporary relief, it's important to consult a healthcare professional for an accurate diagnosis and appropriate treatment. Some of the most popular home remedies for folliculitis include:


1. Turmeric (Haldi): It is known for its anti-inflammatory, antimicrobial, antioxidant properties that can help with various skin conditions.

Make a paste of turmeric powder and water or coconut oil and apply it to the affected region. Allow it to sit for 20-30 minutes before rinsing. Repeat once or twice a day.

Buy the best quality turmeric products online.


2. Apple cider vinegar: It possesses antimicrobial properties that can help combat bacterial infections. 

Mix equal parts of raw apple cider vinegar and water, apply to the affected area, leave for 15-20 minutes, and repeat several times daily.

4. Tea tree oil: Tea tree oil has natural antibacterial and anti-inflammatory properties that may help with folliculitis.

Mix diluted tea tree oil with a carrier oil, apply to the affected area, leave for 20-30 minutes, and repeat 2-3 times daily.


5. Warm compresses: Applying warm compresses to the affected area can help soothe inflammation and promote healing. 
Soak a clean washcloth in warm water, wring out excess moisture, and gently place it on the affected area for 10-15 minutes. Repeat several times a day.

Folliculitis worsens with scratching and can lead to bacterial infections. Soothe the itch with cold moisturizers or gels.

Complications Of Folliculitis

 

While most cases of folliculitis are mild and resolve on their own, certain complications can arise in more severe or persistent cases.
Here are some possible complications of folliculitis:

1. Furuncles and carbuncles: Furuncles are large, painful boils that occur when the infection spreads to the surrounding tissues. Carbuncles are a cluster of interconnected furuncles.

2. Cellulitis: If folliculitis spreads to the surrounding skin, it can lead to cellulitis, a bacterial skin infection that causes redness, warmth, swelling, and pain.

3. Abscess formation: In some cases, folliculitis can lead to the formation of abscesses, which are pockets of pus within the skin.

4. Scarring and hyperpigmentation: Severe or chronic folliculitis can cause scarring and hyperpigmentation (darkening of the skin) in the affected areas.

5. Recurrent or chronic folliculitis: In some individuals, folliculitis may become a recurrent or chronic condition, leading to repeated episodes of inflammation and infection.

6. Spread of Infection: Although rare, folliculitis can potentially spread to other parts of the body through the bloodstream or lymphatic system. This can result in more serious infections, such as bloodstream infections (bacteremia) or deep tissue infections.

A robust immunity is the key to fighting any infection.

Alternative Therapies For Folliculitis


The efficacy of the following complementary therapy needs to be evaluated further and always consult your doctor before trying anything new.

Botulinum toxin A

Studies have shown that Botulinum toxin A can be used as an alternative treatment for folliculitis decalvans by reducing inflammation and inhibiting excessive sweating, which contributes to the condition's development.
