Explanation

Hair loss can happen if you don't get enough of certain nutrients in your diet.

Key Nutrients Associated with Hair Loss:

  1. Iron: Iron is very important for healthy hair. When you don't get enough iron, it can make your hair fall out. This is because iron helps your blood carry oxygen to your hair roots, which is needed for hair to grow.

  2. Zinc: Zinc helps your hair grow and stay healthy. Without enough zinc, your hair might become weak and fall out.

  3. Vitamin D: Vitamin D is also important for hair health. Not having enough vitamin D can make your hair thin or fall out.

  4. B Vitamins: B vitamins, like B12 and biotin, help your hair grow. If you don't get enough of these, you might notice more hair falling out.

Eating a balanced diet with these nutrients can help keep your hair strong and healthy. If you think you might be missing any of these nutrients, it's a good idea to talk to a healthcare provider.
