One lesser-known benefit of bananas is their magnesium content. Magnesium helps relax blood vessels, improving circulation throughout the body—including your scalp.
Why does that matter? Increased blood flow to the scalp brings with it more oxygen and nutrients, which your hair follicles need in order to grow healthy, vibrant hair.
To take it a step further, try combining a banana hair mask with a gentle scalp massage. The combo of topical nourishment and stimulated circulation can do wonders for hair health.
