You’ve noticed more hair in your brush or circling the drain after a shower, and it’s natural to wonder what’s behind the change. While genetics and hormones are common culprits, a factor that often flies under the radar is your iron levels. The connection between what’s happening on your head and what’s happening inside your body might be closer than you think.
The Iron and Hair Growth Connection
Iron plays a vital role in our overall health, but its importance for hair is specific. Your hair follicles are some of the fastest-growing cells in your body, and they need a steady supply of oxygen and nutrients to function properly. Iron is a key component of hemoglobin, the protein in red blood cells that carries oxygen. When iron is low, your body may prioritize sending oxygen to essential organs over your hair follicles. This can interrupt the natural growth cycle, potentially leading to increased shedding and slower regrowth.
Recognizing the Signs of Low Iron
Hair loss from low iron often looks like a general thinning all over the scalp, rather than a receding hairline or distinct bald patches. You might also experience other tell-tale signs that point to an iron deficiency. These can include feeling unusually tired or weak, having pale skin, experiencing shortness of breath, feeling dizzy, or having cold hands and feet. If you’re noticing a combination of these symptoms along with hair changes, it’s a good idea to pay attention.
What to Do If You Suspect Low Iron
If this sounds familiar, the most important step is to talk to your doctor. They can order a simple blood test to check your ferritin levels, which measures your body’s stored iron. Self-treating with supplements isn’t recommended, as too much iron can be harmful. Your doctor can provide a proper diagnosis and recommend the right dosage if a supplement is needed. In the meantime, you can support your iron levels by including more iron-rich foods in your diet, such as lean red meat, spinach, lentils, and fortified cereals. Pairing these with a source of vitamin C, like a glass of orange juice, can help your body absorb the iron more effectively.
While low iron can be a contributing factor to hair loss, it’s often one piece of a larger puzzle. Addressing a deficiency can be a positive step toward not only feeling better overall but also creating a healthier environment for your hair to grow. A conversation with your healthcare provider is the best starting point on that journey.
