Natural Remedies for Gray Hair

I've been taking Iodoral capsules about 2 months and my hairdresser cannot believe my totally white hair now has about 15% restored colour. Not my natural colour however, its dark brown. I used to be a redhead! However red hair does tend to fade with age. I wish I'd known I had sever iodine deficiency years ago, as I was 50% grey by age 35 and 100% by age 45ish. Red hair goes white not grey for some reason. Answer is yes. My hairdresser thinks its a miracle and said I have magic hair! She never saw this happen before. I am taking a fairly high dosage original reason was for heavy metals, fluoride, have amalgam fillings still.
