Some people swear by natural hair loss supplements. Others stand by ingredients like saw palmetto, iron, onion juice or pumpkin seed oil. Some studies show promising results for natural remedies but the numbers are small, and more research is needed to know if they really work. It’s also important to note that too much of certain nutrients (like vitamins A and E and selenium) may actually cause hair loss. If you’re concerned about losing your hair, try to treat it gently, eat a healthy diet and talk to your HCP for ideas and treatment options.
