From the Guidelines
Seborrheic dermatitis is treated with a combination of antifungal and anti-inflammatory medications, with ketoconazole being a key component in various formulations. When considering treatment options for seborrheic dermatitis, it's crucial to prioritize morbidity, mortality, and quality of life as outcomes. Although the provided study 1 primarily focuses on narrowband ultraviolet B phototherapy for psoriasis and atopic eczema, it mentions that seborrheic dermatitis has been shown to respond to TL-01 in an open, prospective study. However, this information is not directly relevant to the most effective treatment approach for seborrheic dermatitis.
For mild cases of seborrheic dermatitis, over-the-counter antifungal shampoos containing ketoconazole 1%, selenium sulfide, zinc pyrithione, or coal tar can be applied to affected areas 2-3 times weekly, leaving on for 5-10 minutes before rinsing.
- Key treatment components include:
- Antifungal agents to reduce the Malassezia yeast population
- Anti-inflammatory medications to control the immune response
- For facial involvement, ketoconazole 2% cream or hydrocortisone 1% cream can be applied twice daily for 1-2 weeks.
- More severe cases may require prescription-strength topical steroids like fluocinolone 0.01% solution for the scalp or desonide 0.05% cream for the face, used for short periods (7-10 days) to avoid skin thinning.
- For maintenance, antifungal shampoos should be used once or twice weekly.
It's essential to note that seborrheic dermatitis is a chronic condition that typically recurs without maintenance therapy, so consistent treatment and avoidance of triggers like stress and harsh skin products are crucial for managing the condition effectively.

From the Research
Treatment Options for Seborrhic Dermatitis
- Topical antifungal agents, such as ketoconazole, are commonly used to treat seborrheic dermatitis of the face and body 4
- For scalp seborrheic dermatitis, over-the-counter shampoos, including antifungal shampoos, can be used as first-line treatment, with topical corticosteroids and calcineurin inhibitors used for short durations as second-line agents 4
- A study comparing ketoconazole 2% and zinc pyrithione 1% shampoos found that ketoconazole 2% was significantly superior in treating severe dandruff and seborrheic dermatitis 5
Alternative Therapies
- Other treatments for seborrheic dermatitis include lithium gluconate/succinate, coal tar, salicylic acid, selenium sulfide, sodium sulfacetamide, glycerin, benzoyl peroxide, aloe vera, and mud treatment 6
- Alternative therapies such as tea tree oil, Quassia amara, and Solanum chrysotrichum have also been reported 6
- A herbal and zinc pyrithione-based shampoo and scalp lotion has been shown to be effective in improving symptoms of seborrheic dermatitis 7
Systemic Therapy
- Systemic therapy, including oral antifungals such as itraconazole, terbinafine, and fluconazole, can be used in severe or unresponsive cases of seborrheic dermatitis 8
- The quality of evidence for oral therapies is generally low, and more research is needed to determine the most effective treatments 8
