Is your dandruff related to your diet? Some experts say it might be, though studies haven't proven that.

"I think research is lagging a bit," says Alicia Zalka, MD, associate clinical professor of dermatology at the Yale School of Medicine in New Haven, Conn. "While there's no compelling data from medical studies that I have found suggesting diet changes can cure dandruff, in my 18 years of clinical practice, more of a connection seems to be emerging."

"A well-managed 'dandruff diet' might help," says Jessica Krant, MD, assistant clinical professor of dermatology at SUNY Downstate Medical Center in New York.

The same diet principles that are good for the rest of you may also make a difference to (if not cure) your dandruff.

When you're making big changes in your diet, it might help to consult a nutrition-savvy doctor or registered dietitian. They can break down exactly what you need. 

Limit Sugar

Most Americans eat too much sugar. Cutting back may lower inflammation, minimizing the appearance of flakes.

"Sugars and simple carbs might promote more inflammation in our bodies, so it makes sense that eating a low-sugar, antioxidant-rich diet could help control dandruff flares," Krant says.

There may also be a hormonal link.

"Diets high in sugar, processed food, and 'bad' fats lead to insulin spikes, which in turn lead to stimulation of hormone surges that can trigger the output of oil," Zalka says. "Overall restriction of fatty foods, fried foods, refined sugar, processed food, and gluten may lead to a reduction in flaking."

Those changes haven't been studied to see if they stop dandruff, but there's no question that they're good for you.
