What Key Factors Should I Consider for Healthy Hair Science?

Healthy hair science involves multiple factors that contribute to hair’s strength, moisture, and overall appearance.

1. Nutrition
2. Hydration
3. Hair Care Products
4. Scalp Health
5. Environmental Factors
6. Genetics
7. Hair Styling Practices
