Nutritional deficiencies can significantly affect both hair structure and growth. These nutrient gaps can trigger:
- Telogen effluvium (TE): Sudden hair shedding is often caused by a drop in calories, protein, or iron
- Androgenetic alopecia (AGA): Can be worsened by low antioxidant status or chronic inflammation
- Alopecia areata: Emerging data suggests immune dysregulation may be influenced by diet
Why Hair Follicles Are So Sensitive
Hair follicles are among the most metabolically active cells in the body. They need:
- Consistent calories and protein
- Steady delivery of iron, B vitamins, D, and zinc
- Protection from oxidative stress
- Hydration
