HAIR AND SYNTHETIC-FIBER ANALYSIS IN FORE NSIC-SCIENCE

Hair is a quite attractive indicator in forensi science because of the chemical stability and the simplicity of sampling and storage. It is also an accessible sample because each person loses approximately a hu ndred hairs per day. Nevertheless, it is a complex material which requ ires sophisticated and as far as possible non-destructive analytical t echniques. We present an overview of the new methodologies in relation to the structural characteristics of hair.
