The 8 Best Vitamins and Supplements for Hair Growth

7. Zinc

Zinc is necessary for the growth and repair of hair tissue. It also aids in the proper functioning of the oil glands surrounding the follicles. A common symptom of zinc deficiency is hair loss.

Zinc supplements have been shown in studies to reduce hair loss caused by zinc deficiency.
However, some anecdotal evidence suggests that supplementing with too high a dose can cause hair loss.

As a result, getting zinc from whole foods may be preferable. Oysters, beef, spinach, wheat germ, pumpkin seeds, and lentils are all high in zinc.
