However, please keep in mind that you will need to provide 7-10 hair samples with the root intact, which can be accomplished by individually plucking the hair from the scalp. Hair that has been shed or that was left on a hairbrush typically will not work, because the root is broken off. It might be simpler (and less painful) to take a buccal swab sample, which usually provides better DNA samples. Before performing the paternity test, we first need to do a viability test on the hair to determine if there is enough usable DNA in the hair samples. Only after this test can we proceed with the DNA test. Testing using a hair sample is just as accurate as testing a buccal swab sample.
