Seborrheic dermatitis and diet

You’ve heard the rumors, but can changing what you eat really cure seborrheic dermatitis? Find out how diet affects seborrheic dermatitis.

You’ll find plenty of theories online suggesting that what you eat can directly affect seborrheic dermatitis (essentially a more severe form of dandruff). But is this true?
One of the most popular theories is that by cutting out ‘yeast-encouraging’ foods like bread, you can reduce the presence of Malassezia globosa (the dandruff-causing microbe) on the scalp and help improve the condition. But there is no evidence that this is an effective treatment.

So far, no meaningful link between diet and seborrheic dermatitis has been published by any regulatory body worldwide, including the FDA.

Malassezia globosa is present on everyone’s scalp regardless of diet and reducing your intake of certain ‘yeast-encouraging’ foods hasn’t been found to reduce Malassezia globosa on the scalp at all.


Head & Shoulders Clinical Strength Shampoo is proven to provide long-lasting protection against Seborrheic dermatitis – its active ingredient, selenium sulfide, is the most effective over-the-counter treatment you can get.

There’s no need to change your diet to tackle seborrheic dermatitis – simply use Head & Shoulders every time you wash your hair to keep it under control.
