Incorporate foods like:

• Eggs and fish for protein and omega-3s
• Leafy greens for iron
• Nuts and seeds for biotin and zinc
• Avocados for healthy fats

A consistent nutrient-rich diet gives your hair the fuel it needs to grow stronger and denser.

Exfoliate your scalp once a week with a gentle scrub or shampoo to remove buildup that blocks growth.
