• Hair Mineral Status in Women with Chronic Fatigue and Depression (Asian J. Pharm. Clin. Res., 2018)
  – Topic: Chronic fatigue, depression, stress, HTMA mineral ratios
  – Key takeaway: Women with fatigue and depression showed lower hair sodium, potassium as well as sodium to magnesium ratios — mineral patterns linked to low energy and mood imbalance.

• Hair Minerals and Heart Health (Nutrients, 2019)
  – Topic: Cardiovascular risk, stress minerals
  – Key takeaway: Hair sodium, potassium, and toxic metals correlate with 10-year cardiovascular disease risk.

• Copper–Zinc Imbalances and Mental Health (Mansoura J. Forensic Med. Clin. Toxicol., 2009)
  – Topic: Mood, anxiety, depression
  – Key takeaway: People with depression or schizophrenia show elevated copper and lower zinc in hair samples.

• Magnesium Status in Children with ADHD (Nutrients, 2020)
  – Topic: Focus, behavior, learning
  – Key takeaway: Children with ADHD tend to have lower magnesium levels in hair than healthy peers.

• Mercury Exposure Reflected in Hair Analysis (Int. J. Environ. Res. Public Health, 2021)
  – Topic: Heavy metals, detoxification
  – Key takeaway: Hair mercury levels provide a more accurate reflection of long-term mercury exposure than blood or urine tests, which capture only recent exposure.

• Hair Trace Elements and Autism Spectrum Disorder (MDPI, 2021 Review)
  – Topic: Neurodevelopment, detoxification
  – Key takeaway: Children with ASD often show elevated toxic metals (As, Pb, Hg) and lower protective minerals (Zn, Mg, Mn) in hair.

• Hair Mineral Patterns and Stress Biomarkers (Biological Trace Element Research, 2013)
  – Topic: Chronic stress, cortisol, burnout
  – Key takeaway: Chronic stress and elevated hair cortisol were linked to lower calcium, magnesium, and zinc levels and a higher calcium-to-magnesium ratio, suggesting that stress-related cortisol elevation disrupts mineral balance and may indicate early adrenal or metabolic strain.

• Hair Tissue Mineral Analysis and Metabolic Syndrome (Biol. Trace Elem. Res., 2009)
  – Topic: Metabolic syndrome, insulin resistance, cardiometabolic risk
  – Key takeaway: Adults with metabolic syndrome showed lower hair Ca, Mg, Cu and higher Na, K and Hg. Optimal Ca and Mg levels were linked to reduced odds of metabolic syndrome, while highest hair mercury was associated with a markedly higher risk.

• Hair Analysis as a Diagnostic Tool in Medicine (Front. Med., 2023 Review)
  – Topic: Clinical validation, overall health assessment
  – Key takeaway: Reviews modern applications of hair analysis in stress, toxicology, and nutritional research.
