Identification methods of human hair products
Near-infrared spectroscopy
1 Scope
This document describes a method for the qualitative identification of human hair and for the determination of fiber content in two-component mixtures of human and animal hair using near-infrared spectroscopy.
This document applies to pure human hair and mixtures of human hair and animal hair with a human hair content ranging from 5.0% to 95.0%.
