Healthy, shiny hair is not just about aesthetics; it reflects overall health and well-being. Achieving lustrous locks requires a combination of proper care routines, a balanced diet, and smart product choices. This article explores the science behind hair health, foods and oils that contribute to shine, practical tips, precautions, and evidence-backed methods to maintain and enhance your hair’s beauty.
The Science of Hair Health
Hair is primarily composed of keratin, a protein that forms the hair's structure, and is surrounded by cuticles, which are protective layers. Healthy, shiny hair results from well-aligned cuticles that reflect light effectively.
Factors affecting hair health include:
- Genetics: Determines hair type, density, and growth rate.
- Diet: Provides essential nutrients for keratin production and scalp health.
- Environment: Sun exposure, pollution, and humidity can damage cuticles.
- Care Routine: Overuse of heat tools, harsh chemicals, and improper washing can strip hair of natural oils, leading to dullness.

Eggs

- Benefits: Biotin promotes keratin production, and protein strengthens hair.

Hydration is Key

Scalp Care
