1. Dark, leafy greens
You’ve likely been told to eat your greens, and you really should heed that advice. Leafy vegetables like spinach and kale deliver a healthy dose of iron that is a mineral needed for healthy hair cells.
Research has linked iron deficiency to hair loss, simply because low iron is an indicator that oxygen and nutrients are not moving to the hair roots and follicles. This can block hair from growing and/or make the hair you do grow, very weak.
