Ca is the most abundant element in the body. It is commonly contained in the bones, but Ca is also actively involved in muscle contraction, the nervous system, hormone secretion, and immune responses. Hair calcium (Ca) levels are correlated with nutritional intake, several disease syndromes, and metabolic disorders.
Some causes of Ca deficiency are:
- inefficient digestion and assimilation
- inadequate dietary intake
- low protein intake
- low vitamin D levels
- excess dietary phosphorus (carbonated drinks are a common source)
When Ca levels are low in the hair, these other essential nutrients are commonly low:
- magnesium
- cobalt
- manganese
- chromium
Others factors associated with low Ca levels:
- lack of physical activity
- chronic stress
- hormone imbalances
- aluminum containing antacids
- chronic use of diuretics and laxatives
- high alcohol intake
- exposure to toxic elements (i.e. lead or cadmium)
Symptoms of Ca deficiency include:
- muscle cramping
- myalgia
- bone pain
- osteoporosis when chronically deficient
Conditions associated with excess Ca include:
- hyperparathyroidism
- osteoporosis
- hypoglycemia
- hormone imbalances
- metabolic disorders
Some hair treatments (permanent solutions, dyes, and bleach) contain excess Ca.
