Thinning hair can benefit from a variety of different treatments and medications, but experts say that your diet and lifestyle really play the biggest role in your hair’s overall health. In fact, Francesca J. Fusco, MD, assistant clinical professor of dermatology at Mount Sinai Hospital in New York City, notes that eating a protein-rich diet helps promote stronger, thicker hair.
“Protein is critical to healthy hair,” she tells Health.com. “Lean meat, fish, poultry, and beans are all great sources. Iron is also important; low iron can lead to anemia, which can lead to increased hair shedding. The great news is that with proper diet and supplementation, this type of hair loss is reversible.”
