Can Dna Be Extracted From Hair Even If The Root Is Not Attached?

Is it possible to extract DNA from hair when the root is absent? The suitability of hair for DNA testing depends on whether there is tissue attached to the root end. When a hair lacks root tissue, an alternative method involves testing for mitochondrial DNA located within the hair shaft itself. This mitochondrial DNA can provide valuable genetic information even in the absence of a root, enabling DNA analysis in various forensic and genetic research contexts.
