A vitamin-rich diet is essential for nourishing healthy hair growth from the inside out. Certain key vitamins support natural keratin production, cell turnover and scalp circulation for thicker, stronger strands over time.

What vitamins are good for hair growth?

Some of the most impactful vitamins that research shows may promote hair follicles include biotin, vitamin C, vitamin E, vitamin A, iron and vitamin B complexes.

Biotin (Vitamin B7)

Biotin aids in keratin synthesis within follicles. Salmon, avocado and walnuts contain this growth vitamin. 200mcg daily supplements also support strands.

Vitamin C

Essential for collagen formation in connective tissue around hair. Red bell peppers, kiwi and broccoli offer vitamin C antioxidants.

Vitamin E

Powerful for moisturizing and strengthening strands. Almonds and sunflower seeds supply this scalp-nourishing vitamin.

Vitamin A

Promotes sebum production to hydrate follicles. Sweet potato, carrots and kale contain beta-carotene precursors to vitamin A.


Transports oxygen for cell turnover in hair roots. Lean red meat, lentils and leafy greens prevent fatigue harming growth.

B-Complex Vitamins

Support growth phases. Salmon, chicken and fortified cereals supply B6, B12, riboflavin, niacin, folate and others.

Aim for variety of these hair-friendly vitamins through nutrient-dense whole foods daily or supplements as needed for thicker strands over time.

Paired with scalp massages and reducing stress, tailored nutrition optimizes follicles' environment to flourish.
