3) Vitamin C
This water-soluble vitamin is a powerful antioxidant that can help your body produce collagen, which supports hair growth. Vitamin C also promotes hair elasticity, meaning it will be less likely to break. To boost your intake of vitamin C, eat foods such as bell peppers, broccoli and citrus fruits—all excellent sources of antioxidants.
Scientists have long known that zinc is a key factor in scalp and hair health, thanks to its vital role in cell growth and repair. One study found that half of men with male pattern baldness were deficient in zinc. If you think you’re experiencing hair loss due to low levels of zinc, supplementing your diet with extra zinc may be an easy fix.
