Hair can trap drug and alcohol biomarkers through multiple routes:
Blood: Biomarkers traveling through the blood vessels enter the root of the hair and become trapped in the core as the hair grows.
Sebum: Sebum is an oily substance that lubricates the growing hair shaft. Drug and alcohol biomarkers in the sebum can be deposited and absorbed by hair.
Sweat: Hair becomes saturated with sweat as we perspire. Biomarkers can be secreted through the sweat glands and are absorbed by the hair shaft.
Environmental Exposure: When drugs are smoked, drug residue in the air can be deposited on and incorporated into the hair shaft.
