Hair can reliably measure average estradiol levels over months in humans and monkeys.
research Abstract # 1697 Hair cortisol concentrations associate with hair growth rate
Hair cortisol levels can indicate stress and are affected by washing frequency, not cosmetic treatments.
research O1: Contribution of in-utero drug exposure when interpreting hair results in young children
Hair analysis alone can't confirm long-term drug exposure in children under 1 year old.
research Testosterone Analysis in Hair
The method shows hair testosterone levels reflect those in saliva, but are affected by various factors and may indicate a risk for heart attack.
research An evaluation of distal hair cortisol concentrations collected at delivery
Distal hair cortisol is not a reliable measure of early pregnancy cortisol levels.
research Premature Graying as a Consequence of Compromised Antioxidant Activity in Hair Bulb Melanocytes and Their Precursors
Gray hair may be caused by lower antioxidant activity in hair cells.
research Involucrin, but not filaggrin and Kdap mRNA, expression is downregulated in 3-D cultures of intact rat hair bulbs after calcium stimulation
Calcium reduces involucrin in rat hair bulbs but doesn't affect filaggrin and Kdap.
research Hair as a retrospective calendar of cortisol production – increased cortisol incorporation into hair in the third trimester of pregnancy
Hair can show increased cortisol levels during late pregnancy.
research Embryology, Histology, and Physiology of the Hair Follicle
The document explains how hair follicles develop, their structure, and how they grow.

Human hair keratin might be good for filtering out harmful substances from water.
research Testing for GHB in Hair by GC/MS/MS after a Single Exposure. Application to Document Sexual Assault
Hair testing can detect a single GHB exposure, useful for documenting sexual assault.
research Radiolabel validation of cortisol in the hair of rhesus monkeys
Hair cortisol can indicate long-term stress levels, but hair growth rate differences may affect accuracy.
