Folliculitis (Acne Folliculitis)
What It Is
Folliculitis is an inflammatory condition affecting the hair follicles, which are responsible for hair production in the skin. It leads to redness, swelling, purulent discharge, and itching. It may present as either acute or chronic.
The most commonly affected areas include the beard, scalp, underarms, genital area, neck, and other regions prone to friction.
It can affect men, women, and children, with a higher incidence in individuals with diabetes, obesity, or those receiving antibiotic therapy. Severe cases may require medical intervention and antibiotic treatment.

Symptoms
Common symptoms include red pimples around hair follicles, often with localized irritation and tenderness. These lesions frequently contain pus. In mild cases, symptoms resolve quickly. In more severe cases, complications such as cellulitis, scarring, or permanent hair loss may occur.
Types of Folliculitis
- Superficial Folliculitis: Affects the upper portion of the follicle, leading to redness or small blisters on the skin’s surface.
•Deep Folliculitis: Involves the entire follicle and causes severe inflammation with painful, boil-like nodules.
• Bacterial Folliculitis: Presents as white pustules filled with pus and surrounding redness. In men, it may appear in the beard area (barber’s itch).
• Fungal Folliculitis: Caused by cutaneous yeasts, mimicking acne. It often worsens with sweating.
• Sycosis Barbae: Occurs after shaving, commonly in men aged 20–40. Severe cases may require medical treatment.
• Gram-Negative Folliculitis: Develops after prolonged use of antibiotics for acne, causing resistant flare-ups.
• Malassezia Folliculitis: A fungal variant that worsens with heat and perspiration.
• Eosinophilic Folliculitis: Associated with immunosuppression; its cause remains unclear.
• Staphylococcal Folliculitis: Caused by Staphylococcus aureus, often associated with ingrown hairs. It may be transmissible between sexual partners and can be misidentified as a sexually transmitted infection.
Causes
Folliculitis can result from various triggers that irritate or damage the follicles:
• Bacteria, fungi, viruses, parasites
• Hot tubs or poorly chlorinated swimming pools
• Shaving against the direction of hair growth
• Excessive sweating
• Friction from tight clothing
• Obesity
• Poor personal hygiene
• Use of occlusive products (e.g. thick creams, sunscreens)
• Diabetes mellitus
Diagnosis
Diagnosis is primarily clinical and based on detailed medical history and physical examination. The dermatologist evaluates the symptoms, severity, and type of folliculitis.
If necessary, a microscopic examination or culture of lesion samples may be conducted to identify bacterial, fungal, or viral pathogens. Additional diagnostic tests are rarely needed unless an underlying condition is suspected.
Treatment
In painful cases, treatment may include topical antibacterial or antifungal agents, oral antibiotics, or drainage of purulent material when required.
For chronic or recurrent folliculitis, laser hair removal may offer a definitive solution by permanently reducing hair growth and minimizing follicular inflammation.
Patients with persistent folliculitis should also be evaluated for possible hormonal imbalances. Advanced therapies may include chemical peels and therapeutic masks to restore skin health.
Prevention Strategies
• Maintain good personal hygiene: Daily showers with mild antibacterial soap can help reduce microbial load.
• Avoid scratching: Refrain from rubbing or scratching irritated skin.
• Wash towels and bed linens frequently: Do not share personal items with others.
• Shave carefully: Use a clean razor blade each time and shave in the direction of hair growth.
• Avoid comedogenic products: Refrain from using oily or heavy creams that clog pores.
• Wear loose, breathable clothing: Prefer cotton over synthetic materials, especially during exercise.
• Use non-comedogenic skincare if you have oily or acne-prone skin.
• Apply antiseptic products regularly to keep the skin clean.
