What food supplement has to be taken to prevent balding of head?

While there is no guaranteed food supplement to prevent balding, some studies suggest that supplements containing biotin, zinc, and vitamins D and E may support hair health. Additionally, omega-3 fatty acids and saw palmetto have also been linked to hair growth. However, it's essential to consult with a healthcare professional before starting any supplement regimen for hair loss. Genetics and hormonal factors play a significant role in balding, so supplements may have limited effectiveness.
