What’s the Impact of Diet on Hair Health: Foods for Stronger, Shinier Locks
Your hair is a reflection of your overall health, and diet plays a critical role in determining its strength, texture, and shine. What you eat can either nourish or deplete your hair, making nutrition an essential factor for luscious locks. This article explores the connection between diet and hair health, highlighting specific foods and nutrients that promote stronger, shinier hair.
How Diet Affects Hair Health
Hair growth and quality depend on the health of your hair follicles, which rely on nutrients delivered through your bloodstream. A nutrient-rich diet fuels the production of keratin, the protein that forms the structure of your hair, and supports a healthy scalp environment.
Signs of Nutritional Deficiencies in Hair
Brittleness: May indicate a lack of biotin or zinc.
Excessive shedding: Could be linked to insufficient iron or protein.
Dryness: Often caused by low omega-3 fatty acids.
