# The 14 Best Foods for Healthy Hair Growth, According to Doctors and Dietians
Hair health begins in the kitchen, not the supplement aisle. Rather than investing in expensive hair growth products, doctors and dietitians recommend focusing on whole foods that deliver the nutrients your hair follicles actually need.
Your hair grows from protein-rich roots, so adequate protein intake forms the foundation of hair health. Eggs contain both protein and biotin, a B vitamin that supports keratin production. The yolk provides choline, which aids nutrient absorption throughout your scalp.
Fatty fish like salmon and sardines deliver omega-3 fatty acids that reduce inflammation around hair follicles. These same nutrients improve blood circulation to the scalp, ensuring follicles receive steady oxygen and nutrients. Walnuts offer a plant-based alternative with similar anti-inflammatory benefits.
Iron deficiency causes hair loss, making iron-rich foods essential. Red meat, lentils, and spinach replenish iron stores that support the hair growth cycle. Pairing iron sources with vitamin C amplifies absorption, so combine spinach salads with citrus dressing or add tomatoes to lentil dishes.
Zinc regulates sebum production and prevents hair shedding. Oysters contain more zinc per serving than almost any other food, though beef, pumpkin seeds, and chickpeas provide reliable plant-based options.
Vitamin A promotes sebum production that keeps scalp and hair hydrated. Sweet potatoes, carrots, and kale deliver beta-carotene, which your body converts to vitamin A. Berries contribute antioxidants that protect hair follicles from oxidative stress caused by free radicals.
Nuts and seeds provide vitamin E, which improves scalp blood flow. Almonds, sunflower seeds, and avocados round
