Best Vitamins & Minerals for Shiny, Healthy Hair

Which vitamins and minerals should I look for in foods for healthy hair shine?

Hair shine is largely a reflection of how smooth the hair cuticle is and how well your scalp and strands are supported from the inside out. When choosing foods (or checking labels on fortified options), focus on nutrients tied to keratin production, healthy oils, and antioxidant protection.

Biotin (Vitamin B7)

Biotin helps support keratin infrastructure, which can influence hair’s strength and overall appearance. Look for biotin-rich foods like eggs (especially yolks), salmon, nuts, seeds, and legumes.

Vitamin C

Vitamin C supports collagen formation and improves iron absorption—both useful for maintaining resilient strands. Citrus fruits, strawberries, bell peppers, broccoli, and kiwi are strong picks.

Vitamin E

Vitamin E acts as an antioxidant and supports scalp health by helping defend cells from oxidative stress. Reach for almonds, sunflower seeds, spinach, and avocado.

Vitamin A (and beta-carotene)

Vitamin A contributes to healthy skin and sebum production, which can help hair look less dull. Choose beta-carotene foods like sweet potatoes, carrots, and leafy greens; avoid overdoing high-dose supplements since too much vitamin A can backfire for hair.

Iron

Iron helps deliver oxygen to hair follicles. If intake is low, hair can look less vibrant and feel weaker. Good sources include lean red meat, lentils, spinach, beans, and iron-fortified cereals (pair plant sources with vitamin C).

Zinc

Zinc supports tissue growth and repair and can help maintain a balanced scalp environment. Find it in oysters, beef, pumpkin seeds, chickpeas, and yogurt.

Selenium

Selenium supports antioxidant defenses and thyroid function, which can influence hair quality. Brazil nuts are very concentrated; seafood, eggs, and whole grains also contribute.

Omega-3s (bonus nutrient for shine)

While not a vitamin or mineral, omega-3 fatty acids help support scalp hydration and hair softness. Fatty fish (salmon, sardines), chia seeds, flaxseed, and walnuts are excellent options.

FAQ

How much protein do I need for shinier, stronger hair?

Aim for steady protein across meals, since hair is primarily made of keratin (a protein). Many people do well targeting roughly 20–30 grams of protein per meal, adjusted for body size and activity level.
