Dandruff and Diet: Can Food Choices Impact Scalp Flakes?

Dandruff (seborrheic dermatitis) involves Malassezia yeast overgrowth, inflammation, and an impaired skin barrier. While diet alone doesn't cure dandruff, certain nutrients support scalp health and may reduce flare-ups.

Potentially Beneficial Foods

• Probiotics (yogurt, kefir, fermented foods): May modulate the skin microbiome and reduce inflammation.
• Omega-3 fatty acids (salmon, sardines, walnuts, flaxseed): Anti-inflammatory; improve skin barrier function.
• Zinc-rich foods (oysters, pumpkin seeds, beef, lentils): Regulate sebum production; support immune function.
• Antioxidants (berries, leafy greens, colorful vegetables): Combat oxidative stress on the scalp.
• B vitamins (eggs, whole grains, legumes): Biotin, B6, B12 support keratin production.

Foods to Limit

• High-glycemic/refined carbs (may increase sebum and inflammation)
• Excess saturated/trans fats
• Alcohol (dehydrating, pro-inflammatory)

Evidence-Based Core Treatment

• Medicated shampoos: zinc pyrithione, ketoconazole, selenium sulfide, ciclopirox, coal tar.
• Rotate active ingredients; leave on 5 minutes before rinsing.
• Consistent use 2–3×/week; maintenance 1×/week.

Diet complements but doesn't replace proven therapies. See a dermatologist if OTC shampoos fail after 4–6 weeks.
