Hair thinning is frequently attributed to genetics, but nutritional imbalances often play a primary role. Critical deficiencies in iron, zinc, vitamin D, and collagen can weaken hair follicles over time, leading to premature shedding and reduced hair density. When follicles lack adequate nutrient support, their natural growth cycles become compromised.

Integrating nutrient-dense foods—such as spinach, eggs, wild salmon, nuts, and bone broth—helps provide the essential building blocks needed to support follicular health. While dietary improvements play a fundamental role in maintaining hair vitality, medical experts advise consulting healthcare professionals to identify and address individual metabolic or hormonal underlying causes.
