TLDR Hair can show daily calcium changes, linked to body calcium levels and influenced by hormones, and can help assess calcium metabolism issues.

The study utilized X-ray fluorescence analysis to observe daily variations in calcium concentration along hair shafts, revealing that hair can record these variations over time. Calcium levels in hair were found to correlate with serum calcium levels, influenced by parathyroid hormone (PTH) secretion, which peaks at night. The research indicated that hair calcium levels decrease with acidosis, characterized by high bromine levels, but can be restored with calcium supplementation. This method demonstrated potential for assessing calcium metabolism disorders through hair analysis.
