TLDR DNA can be quickly and effectively extracted from hair using laundry powder.
A method was developed to extract DNA from hair shafts using enzymatic laundry powder and PCR buffer, completing the process in under 2 hours. The method was validated using fluorescence spectroscopy and PCR, showing good efficiency and repeatability. This approach was expected to enhance the use of hair shafts for genome-wide DNA analyses.
