Re: Grey Hair = Paba deficiency

I though the reversal of grey hair with PABA was temporary and that if you stopped taking PABA your hair went back to grey fairly soon.
I just checked my hair (not easy since I die it with henna) and I think my roots may possibly be darker than they were when I started Iodine.
On the other hand, since starting Iodine my husband has seen a lot more white hair on the temples.
Don't know what to rhink!
