Why Vitamins Matter for Skin and Hair Health

Vitamins support:

  • Collagen synthesis

  • Hydration and cellular repair

  • Hair follicle strength

  • Antioxidant protection

  • Skin barrier health

This is why including vitamin-rich foods or supplements when necessary can significantly improve both skin and hair health.
