The Best Supplements for Aging Hair and Nails: Expert Recommendations

A dermatologist recommends four essential nutrients for maintaining healthy hair and nails: biotin, zinc, iron, and pumpkin seed oil. While it's best to obtain these nutrients from natural food sources, supplements can be beneficial if needed. Biotin boosts collagen production and hair growth, zinc is critical for hair growth, pumpkin seed oil aids in hair growth for thinning hair, and iron promotes healthy hair growth by boosting circulation. A multivitamin can also be beneficial for overall health.
