Answer: Hope this helps!

Step-by-step explanation:

When performing a hair DNA test for the purpose of paternity, it is a must to have a complete hair sample – with hair shaft and hair follicle. On the other hand, if the purpose of hair DNA testing is for forensic use, a cut hair sample even with no follicle can still be of use. However, a complex procedure has to be made.
