Is it possible to do DNA tests on hair samples?
Yes, DNA extraction from a hair sample freshly taken from the scalp with the hair follicle still intact and attached to the hair shaft provides the best results. The results from non-standard samples depend very much on the condition of the sample. For example, if hairs are sent without roots or as shed hair the results are generally poor.

For a DNA extraction from a hair sample it is best if the hair is freshly pulled out/ taken from the head and that the hair follicle is still intact to the hair strand to get the best extraction results. The results from non-standard samples (as hair) depend very much on the condition of the sent sample. For example if hairs are sent, it is best if more than 5 hairs with root are pulled out from the head and sent for testing (hair without a root or shed hair do not give good results).
