Proper handling and storage of hair samples, as well as thorough cleaning and analysis techniques, are crucial in obtaining accurate results.

To illustrate the accuracy of DNA tests conducted from hair samples, let's consider a real-life example. In the infamous case of Ted Bundy, a notorious serial killer, DNA testing was carried out on hair samples found at crime scenes. Nuclear DNA testing was used to match the DNA in the hair samples to the known DNA profile of Ted Bundy, providing strong evidence of his involvement in the crimes. This example showcases the accuracy and importance of using properly conducted DNA tests on hair samples in solving criminal cases.

In conclusion, DNA tests conducted from hair samples can be highly accurate, depending on the type of test and the quality of the sample. Nuclear DNA testing, when performed on hair samples with roots or follicles, can provide conclusive matches between a sample and an individual. MtDNA testing, on the other hand, is less accurate for individual identification but can provide information about maternal lineage. The accuracy of these tests can be affected by the quality of the sample and proper procedures must be followed to minimize contamination and degradation. Overall, DNA testing from hair samples has played a crucial role in forensic investigations and continues to be a valuable tool in identifying individuals and solving crimes.
