Tissue salts have been put forth as one possible cause of hair loss...
The taking of an iodine/ide supplement in larger doses (very different for different people) could very easily, and most likely does, throw the "balance" of cellular tissue salts off.
Think... first there was the addition of salt loading to the iodine/ide protocol, and now ACV for the hair loss issue experienced by some people. Also the , additional recommendation of magnesium, selenium, any number of minerals (salts). Put 2 + 2 together...
EDIT
For hair loss...
Hair loss
NR. 3 Ferrum phosporicum D12
NR. 5 potassium phosporicum D6 in the change also
NR. 11 Silicea D12 in the change also
2x daily ever 2 tablets
Sodium salt loading may not be a good idea for this, further exacerbating the problem...
