I've been on the protocol for nearly a year and reached the 50 MG dose about 2 months ago. This dosage has totally stopped my hair loss. I didn't even realize that my hair was falling out that much until it stopped completely! I've always had curly hair, but noticed the past few years that I was losing my curl and just seemed not as healthy. My hairdresser blamed hormones. Apparently, it was an Iodine deficiency because it is getting curlier and thicker. It's almost as if I'm pregnant. I barely shed a hair anymore. I just thought I'd share another exciting effect of iodine:).
