Can hair analysis detect nutritional deficiencies?

Prof. William Dalton, Ph.D.Hair mineral analysis provides insight into mineral deficiencies, such as zinc or selenium deficiencies, through a longitudinal mapping of the hair shafts. Unlike blood tests that measure current levels, this method illustrates a pattern over several months. This process helps us diagnose chronic deficiencies that we would not be able to identify through other tests.
Zinc Deficiency Indicators
- Consistent levels below 120 ppm indicate deficiency
- Links to impaired immune function and hair loss patterns
- Requires 3 months of low readings for confirmation
- Correlates with taste perception changes
Selenium Imbalances
- Readings under 0.5 ppm compromise antioxidant defenses
- Associated with thyroid dysfunction markers
- Shows geographic patterns in soil-deficient regions
- Requires blood test confirmation for clinical diagnosis
Iron Status Clues
- Low ferritin correlates with hair mineral patterns
- Brittle hair and slow growth indicate possible deficiency
- Cannot replace serum ferritin tests for anemia diagnosis
- Patterns require correlation with blood work
Vitamin deficiencies cannot be evaluated through testing hair. A mineral deficiency (such as zinc) may suggest that there are problems with vitamin B, but a blood test will be needed. Hair indicates mineral transportation methods but does not indicate direct blood vitamin levels.
Incorporating hair analysis with blood tests allows for a comprehensive assessment of nutrients. Hair will reveal mineral levels over the long haul, while blood will tell you about acute vitamin status. This combination will consider problems related to absorption and metabolic functions.
Interpretation requires professional expertise. Mineral ratios like calcium-magnesium above 10:1 suggest metabolic stress. Certified nutritionists correlate hair data with symptoms and dietary history for accurate deficiency diagnosis.
