When I first started taking Iodine I would get them on the side of my neck. Really BIG cysts.
I have never had Acne so this was an interesting twist for someone in their mid forties:) This lasted for a month or so, I then started to get them on my Chin and forehead and in my Hair.
The Acne on my chin and forehead has cleared up but I still get one or two pimples a week in my hair. I dyed my hair from the age of 20 or so up until a year ago. I believe that I am detoxing something out of my hair follicles from the hair dye.
