Hair evidence collected as part of a forensic investigation has the potential to provide valuable source information through DNA analysis of its root. This webinar discusses the process of utilizing Hematoxylin staining in forensic casework as an indicator of hair root DNA suitability. The presenters demonstrate the process of staining hair roots with Hematoxylin, as well as provide visual examples of stained hair roots. This webinar also highlights the benefits of implementing hair root staining into casework in terms of increased DNA yields, improved casework efficiency, and preservation of non-viable hair root evidence.
