# 15 Best Foods For Growing Stronger, Thicker Hair
Hair growth starts from the inside out, and registered dietitians now confirm what nutrition science has long suggested: the foods your family eats directly shape hair quality, thickness, and strength.
Protein forms the foundation of healthy hair. Hair strands consist primarily of a protein called keratin, so children and teens need adequate protein daily to support growth. Lean meats, eggs, Greek yogurt, and legumes all deliver the amino acids hair follicles require.
Iron matters too. Low iron stores lead to hair shedding and slower growth, particularly in children and adolescent girls. Red meat, spinach, lentils, and fortified cereals boost iron levels.

Omega-3 fatty acids nourish the scalp and reduce inflammation that can interfere with hair growth. Salmon, walnuts, flaxseeds, and chia seeds pack these essential fats. Even picky eaters often tolerate salmon mixed into pasta or hidden in baked goods.
