How do I treat dandruff and seborrheic dermatitis of the scalp?
Unfortunately, there is no magic "cure" for these conditions. However, most symptoms can be controlled and treated with over-the-counter medicated shampoos. These shampoos use three different approaches for symptom control:
Slow down the process: Shampoos with coal tar help slow the proliferation (overproduction) of skin cells on the scalp, and reduce potential inflammation.
Clear scalp buildup: Shampoos with salicylic acid help break down scalp buildup and split flakes into smaller, less visible pieces that can be washed away easily. A shampoo with salicylic acid can be used as a primary shampoo or as a first step in a scalp treatment regimen, especially for those with significant flaking and buildup.
Remove the yeast: Shampoos containing pyrithione zinc, ketoconazole, or selenium sulfide remove yeast, a potential scalp irritant, from the scalp.

If your current medicated shampoo is not controlling or improving your symptoms, try switching to one with a different active ingredient. Dermatologists may recommend “rotational therapyâ€â€”using specific products on alternating days to attain the best results when treating scalp conditions. For example, severe scalp symptoms may be treated by shampooing twice a week with a product containing salicylic acid to clear flake and sebum buildup, and shampooing on other days with a product containing coal tar to control flake formation. Always follow the instructions provided with medicated shampoos and conditioners. Once symptoms clear, weekly use will help prevent further flare-ups.
Occasionally, severe scalp conditions may require treatment with a prescription-strength shampoo, cream, or ointment. Your dermatologist can provide you with specific advice on treating serious scalp problems.
