How To Stop Iodine Deficiency-Related Hair Loss

The quickest and most effective way to stop hair fall caused by iodine deficiency is to use white (decolorized) iodine. When applied topically on areas that are experiencing hair loss, white iodine can get absorbed into your scalp and enter your bloodstream to boost hair growth. It has shown promising results in treating bald spots caused by alopecia. Another way it combats hair fall is by attacking any fungal infection that could be feeding on your hair follicles and weakening your hair. So, here’s a simple way that you can use it…

What You Need
  • White iodine (It comes in a bottle in liquid form and is easily available in drugstores)
What To Do
  1. Wash your hair as usual and let it air dry.
  2. Once your hair and scalp are completely dry, apply some white iodine on areas that are experiencing hair loss.
  3. Gently massage it into your scalp to ensure maximum absorption.
  4. If using white iodine directly on your scalp causes irritation, dilute in a couple of tablespoons of water before applying it.
  5. Repeat this application every day to see effective results. You can also apply white iodine twice a day on areas that have too much hair loss.
