Silica provides strength to your hair, and although it will not necessarily stop your hair from falling out from the follicle, it will stop hair breakage.

Foods that are rich in silica are rice, oats, lettuce, parsnips, asparagus, onion, strawberry, cabbage, cucumber, leek, sunflower seeds, celery, rhubarb, cauliflower, and swiss chard.
