Corrected entry: In the second episode of season 2, Amanda tricks Bradford into giving her his hair for DNA samples. However, she goes in with a buzz clipper, which only trims the hair and DNA is only available in the root of the hair, so she couldn't have gotten DNA from him.

Correction: You CAN use hairs for DNA-testing, but it will only be mitochondrial DNA (DNA inherited from the mother) so it won't be much good.
