Can a DNA test be done with a strand of hair?
The Science Behind Hair DNA Testing
DNA testing through a strand of hair is not just a plot device in science fiction but a reality backed by robust scientific principles. The key to a successful DNA test from hair lies in the root. A hair follicle at the root contains cellular material rich in DNA. When a hair is plucked, and the root is intact, it can serve as a viable source for DNA analysis. This process, however, hinges on the presence of the root - hair shafts alone, without the root, typically do not contain sufficient DNA for testing.
