YES ! Try this.... Mix water with Lugols and spray into your armpits each morning. Chemical free anti-deoderant. Mix 1/4 Lugols 2% & 3/4 water.
The reason you have odor is because of bacteria thriving in your armpits. A weak solution of Iodine safely KILLS all bacteria. It must be diluted with water so as not to irritate your skin.
PS) My diluted Iodine treatment to my scalp is still a success! Over 1 month now and STILL no new dandruff. AMAZING !
