Quoting from the above link ---
"
When the hair tissue calcium level is high relative to sodium and potassium, one loses calcium into the tissues. It precipitates into the tissues because low sodium and potassium levels cause calcium to come out of solution in the blood.
Sodium and potassium are required to solubilize or maintain calcium in a soluble or ionized form in the blood. When sodium and potassium are deficient due to weak adrenal and/or thyroid activity, some calcium drops out of solution and precipitates into the tissues including the hair.
As calcium leaves the blood and precipitates into the tissues, calcium may be withdrawn from the bones to replace the calcium lost from the blood. If this continues for years, one develops osteoporosis. For this reason, Paramin is now given to all slow oxidizers as well as fast oxidizers. "
