Yes, hair can be used for DNA testing, but it depends on the type of test and the hair sample.
- For forensic investigations, hair samples are commonly used, especially when the root is present. This is because the root contains cells with nuclear DNA, which can be used to identify individuals.
- For ancestry or paternity tests, hair samples are less reliable. Most companies require a cheek swab for these tests, as it provides a larger and more readily accessible source of DNA.
- Some companies offer hair DNA testing, but they often specify that the hair must have the root attached. This is because the root contains more DNA than the shaft.
It's important to note that not all DNA testing companies accept hair samples, and the accuracy of the test can vary depending on the quality of the sample.
