From the Guidelines
Dandruff can be effectively treated with over-the-counter anti-dandruff shampoos containing active ingredients like pyrithione zinc, selenium sulfide, ketoconazole, coal tar, or salicylic acid. For best results, apply the shampoo to wet hair, massage into the scalp, leave on for 5 minutes, then rinse thoroughly. Use the medicated shampoo daily until symptoms improve, then 2-3 times weekly for maintenance. Alternate between different active ingredients if one becomes less effective over time. For severe cases that don't respond to over-the-counter treatments, prescription-strength ketoconazole shampoo or topical steroids may be necessary.
Key Considerations
- Dandruff occurs when the normal skin renewal process accelerates, causing dead skin cells to accumulate and flake off, often triggered by a yeast called Malassezia that naturally lives on the scalp 1.
- The active ingredients in anti-dandruff shampoos work by either slowing skin cell turnover, reducing inflammation, or controlling the yeast population.
- Additionally, reducing stress, maintaining proper scalp hygiene, and avoiding hair products that may irritate your scalp can help manage dandruff long-term.
Treatment Options
- Over-the-counter anti-dandruff shampoos with active ingredients like pyrithione zinc (Head & Shoulders), selenium sulfide (Selsun Blue), ketoconazole (Nizoral), coal tar (Neutrogena T/Gel), or salicylic acid (T/Sal) are effective for treating dandruff.
- Prescription-strength ketoconazole shampoo or topical steroids may be necessary for severe cases that don't respond to over-the-counter treatments.
Important Notes
- Topical agents, including shampoos, are considered first-line treatment for dandruff and are recommended by experts, despite weak evidence from the literature 1.
- Patient preferences and compliance are crucial in determining the effectiveness of topical therapies, as application can be time-consuming and demanding 1.
From the Research
Dandruff Treatment Options
- Dandruff is a common complaint that can be treated with various shampoos and ingredients, including salicylic acid, tar, selenium, sulfur, and zinc 2
- Antifungal shampoos, such as those containing selenium sulfide, imidazoles, or ciclopirox olamine, can help reduce Malassezia scalp reservoirs and alleviate dandruff symptoms 2
- Shampoos containing piroctone olamine and salicylic acid have been shown to be effective in reducing dandruff severity and area affected by scaling 3
- Combination shampoos, such as those containing zinc pyrithione and climbazole, can provide superior efficacy and sensory properties, making them a desirable option for dandruff treatment 4
Comparison of Dandruff Treatments
- A study comparing ketoconazole 2% and zinc pyrithione 1% shampoos found that ketoconazole was significantly more effective in alleviating severe dandruff and seborrheic dermatitis 5
- Another study compared the therapeutic efficacy of shampoos based on potentiated zinc pyrithione and zinc pyrithione/climbazole, finding that the potentiated zinc pyrithione formula exhibited greater anti-fungal potency and clinical efficacy 6
- The choice of dandruff treatment may depend on individual preferences and needs, as well as the severity of symptoms 2, 3, 4, 5, 6
Key Ingredients for Dandruff Treatment
- Zinc pyrithione is a common ingredient in anti-dandruff shampoos, with studies showing its effectiveness in reducing dandruff symptoms 4, 5, 6
- Salicylic acid is another ingredient that has been shown to be effective in treating dandruff, particularly when combined with other ingredients such as piroctone olamine 2, 3
- Ketoconazole is an antifungal ingredient that has been found to be effective in treating severe dandruff and seborrheic dermatitis 5
