Hair loss can be a frustrating experience, and sometimes it’s linked to a lack of iron. Iron is crucial for making haemoglobin, which carries oxygen to your cells. Without enough iron, your hair follicles may not get the oxygen and nutrients they need, which can lead to hair thinning and loss.

If iron deficiency is causing your hair loss, taking iron supplements can help. These supplements work by boosting your iron levels, which supports your hair follicles and helps stop further hair loss. If iron deficiency is the only reason for your hair loss, you should start seeing improvements within a few months of taking iron supplements.

Typically, it takes about 3 to 6 months to see noticeable changes, as hair growth is a gradual process. 

How much iron to take for hair loss?

Finding the right amount of iron to address hair loss involves understanding your specific needs and current iron levels. For most adults, the recommended daily amount of iron is about 18 mg for women and 8 mg for men. If you have iron deficiency, your healthcare provider might suggest a higher dose to help correct it.

Iron supplements come in different forms, such as ferrous sulphate, ferrous gluconate, and ferrous fumarate. Your provider will help you choose the best option and dosage for you.
