How do you extract DNA from human hair?

A simple method to extract DNA from hair shafts was developed by using enzymatic laundry powder at the first step of the process. The whole extraction can be finished in less than 2 hours.

Until now, forensic scientists have only been able to extract DNA from hairs found at crime scenes if they have their root attached. Unfortunately, most hairs do not have the root attached, so using DNA sampling to discover whom it belonged to has been impossible.

Can you isolate DNA from hair?

There are two parts to hair from which DNA can be extracted and isolated: the hair follicle and the hair shaft.
