Nizoral A-D Anti-Dandruff Shampoo (Ketoconazole 1%)
Pityrosporum folliculitis - fungal folliculitis caused by *Malassezia* overgrowth - is the most commonly missed form of scalp folliculitis because it looks nearly identical to bacterial folliculitis and does not respond to antibacterial washes. It is characterized by monomorphic (all the same size and stage), itchy papules and pustules that tend to worsen with oily scalp conditions, humidity, and heat. Ketoconazole is the most effective OTC antifungal available for Malassezia, and Nizoral A-D is the only ketoconazole 1% shampoo in the OTC market.

Medical Disclaimer: Scalp folliculitis can have multiple causes including bacterial infection, fungal overgrowth (pityrosporum folliculitis), and other conditions that require different treatments. Widespread folliculitis, deep nodules, scarring, hair loss, or lesions that do not respond to OTC treatment within 2-3 weeks warrant dermatologist evaluation. These products are appropriate for mild-to-moderate folliculitis in otherwise healthy adults. Immunocompromised individuals should seek medical advice before self-treating.
Scalp folliculitis is inflammation of the hair follicles on the scalp, presenting as itchy red bumps, pustules, or papules at or around the follicle opening. The condition has two primary OTC-addressable forms: bacterial folliculitis (most commonly Staphylococcus aureus driven) and fungal folliculitis (Malassezia/pityrosporum), which look similar but require different approaches. A third form – acne keloidalis nuchae – affects the back of the scalp and hairline and almost always requires dermatologist management. Identifying which type you have guides product selection; the products below cover the most common forms.

Nizoral A-D Anti-Dandruff Shampoo (Ketoconazole 1%)
Pityrosporum folliculitis - fungal folliculitis caused by *Malassezia* overgrowth - is the most commonly missed form of scalp folliculitis because it looks nearly identical to bacterial folliculitis and does not respond to antibacterial washes. It is characterized by monomorphic (all the same size and stage), itchy papules and pustules that tend to worsen with oily scalp conditions, humidity, and heat. Ketoconazole is the most effective OTC antifungal available for Malassezia, and Nizoral A-D is the only ketoconazole 1% shampoo in the OTC market.
Jason Dandruff Relief 2-in-1 Shampoo (Zinc Pyrithione 2% + Sulfur)
Jason Dandruff Relief stands out from standard zinc pyrithione shampoos because it combines zinc pyrithione 2% with sulfur - a combination that provides both antifungal and mild antibacterial activity. Zinc pyrithione disrupts cell membrane function in both bacteria and fungi; sulfur adds a secondary antibacterial layer while also mildly reducing oiliness. For cases where it is unclear whether folliculitis is bacterial or fungal in origin (a common situation), this dual-action formula covers more ground than single-ingredient products.
Tree To Tub Soapberry Shampoo for Sensitive Scalp
Scalp pH matters more than most people realize. Healthy scalp skin has a slightly acidic pH of around 4.5-5.5, which inhibits pathogen overgrowth and supports the skin microbiome. Many conventional shampoos have a pH of 6-8, which disrupts this protective barrier. Tree To Tub Soapberry Shampoo is formulated at a pH of 4.5-5.5 using soapberry (Sapindus mukurossi) as the primary surfactant - a plant-derived cleanser that creates a gentle lather without stripping the acid mantle.
The Ordinary Multi-Peptide Serum for Hair Density
Scalp folliculitis can compromise follicle integrity over time - repeated inflammation damages the follicle wall, potentially leading to miniaturization and temporary hair thinning. The Ordinary Multi-Peptide Serum for Hair Density is a leave-on scalp serum containing a range of peptides and plant actives that support follicle health, reduce scalp inflammation, and promote healthy hair cycling. It is not a folliculitis treatment in itself, but it supports the recovery phase and helps maintain follicle integrity during and after treatment.
Noble Formula 2% Pyrithione Zinc Bar Soap
Noble Formula's 2% pyrithione zinc bar soap is the most concentrated zinc pyrithione format available OTC. While shampoos are rinsed off quickly, a bar soap allows for a more controlled leave-on application on the scalp - work it into a lather directly on the scalp, leave for 2-3 minutes, rinse. The bar soap format also makes it easy to apply to the back of the neck, hairline, and ears where folliculitis frequently extends beyond the central scalp. It contains emu oil which some users find conditioning, though this is a secondary benefit.
Before you buy
Identify bacterial vs. fungal before treating
Fungal folliculitis (pityrosporum) needs ketoconazole or zinc pyrithione. Bacterial folliculitis needs antibacterial washes, and moderate-to-severe cases need prescription antibiotics. The wrong treatment wastes weeks.
Scalp hygiene practices
Wash hair promptly after sweating, avoid heavy scalp oils during active folliculitis, reduce hat and helmet use when possible, and avoid touching or picking at pustules (which spreads bacteria and increases scarring risk).
When to see a dermatologist
Spreading infection, hair loss, scarring, deep or painful nodules, no improvement after 2-3 weeks of correct OTC treatment, or any fever accompanying scalp folliculitis all warrant prompt dermatologist evaluation.
Consider comedogenic products
Hair oils, silicones, and greasy styling products applied near the scalp can exacerbate folliculitis by clogging follicle openings. Switching to lighter, water-based styling products during treatment often helps.

Quick answers
Bacterial folliculitis (usually Staphylococcus aureus) presents as small red or pus-filled bumps at the hair follicle base, often after shaving, wearing tight headwear, or sweating. Fungal folliculitis (Malassezia-driven pityrosporum folliculitis) presents as monomorphic itchy papules and pustules, often worsened by oily skin, heat, or sweating. Antifungal shampoos like ketoconazole treat fungal; bacterial forms may require topical or oral antibiotics.
See a dermatologist if folliculitis is spreading, forming deeper nodules, causing hair loss, leaving scars, not responding to OTC treatment within 2-3 weeks, or is accompanied by fever. Severe or recurrent cases may need prescription oral antibiotics (for bacterial) or prescription-strength antifungals. Carbuncles (deep, fused follicle infections) always need medical evaluation.
Yes. Friction from tight hairstyles (traction), occlusion from hats or helmets trapping sweat and heat, and frequent product buildup all create conditions favorable for folliculitis. Reducing hat use when possible, switching to breathable headwear, avoiding heavy oils near the scalp, and washing hair promptly after sweating are all effective preventive hygiene practices.
