Can you do a DNA test with hair?

If you need to collect hair samples for DNA analysis, the only way to ensure accuracy is by having laboratory personnel or law enforcement officials, as well as a forensic examiner pluck out the strand at its root. Cutting it will not suffice! That said, make sure that whoever performs this task has expertise in collecting such specimens and understands how crucial proper collection technique is when conducting DNA tests.

What Is A DNA Test?

A DNA test is a scientific procedure that examines the unique genetic makeup of an individual. It can be used in many different areas such as ancestry research, forensics, paternity testing, health screening, and more. Because everyone has a unique set of genes, the results from a DNA test can help identify relationships between individuals or verify certain traits or characteristics.

How Does A Hair-Based DNA Test Work?

For the most part, hair-based tests work in much the same way as other forms of DNA testing. The main difference is that instead of using saliva or blood samples for testing, hair samples are used instead. To collect your sample, all you have to do is pluck out some hairs from your head or body (if they are still attached to the follicle). The hairs should then be placed into an airtight container and sent off for analysis in a lab.

The lab technicians will then extract the cells from your hair sample and look at their genetic makeup through specialized procedures such as polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). Once they have identified certain markers within your genetics, they can compare them against those found in other samples for comparison purposes. This process helps them determine not only who you are related to but also provides insights into things like inherited conditions and family history.


Whether you’re interested in conducting paternity tests or researching your ancestry, there are plenty of reasons why you may want to consider doing a DNA test with hair. By looking at your unique genetic makeup through specialized laboratory procedures like PCR or RFLP analysis, labs can provide valuable insights about who you are related to as well as any inherited conditions or family history that may be present in your genes. With how easy it is to collect your own sample and send it off for testing, there’s no reason not to give it try!


How accurate is a hair-based DNA test?

Hair-based DNA tests are highly accurate, provided the sample has been collected and handled properly. By using laboratory techniques such as PCR or RFLP analysis, labs can accurately identify any markers present in the sample and compare them against other samples for comparison.

Can you do a DNA test with hair from any part of the body?

Yes, you can use hairs from any part of your body as long as they are still attached to the follicle. However, it is best to collect samples from the head or chest area for maximum accuracy.

Is it safe to do a hair-based DNA test?

Yes, collecting a hair sample for DNA analysis is perfectly safe. There is no risk of contamination or any other safety concerns associated with the collection process. Additionally, all laboratories must adhere to strict guidelines and regulations when it comes to handling samples in order to ensure accurate results.

How long does it take to receive the results from a hair-based DNA test?

It depends on the lab, but generally you should expect to receive your results within 2-4 weeks after submitting your sample. This timeframe can vary depending on factors such as how busy the lab is or how thorough their testing procedures are.

How much does a hair-based DNA test cost?

The cost of a hair-based DNA test can vary depending on the lab and what type of analysis they are performing. Generally, you should expect to pay anywhere from $100-$200 for a basic test, with more complex tests costing up to several thousand dollars. Prices can also vary depending on the turnaround time you need for your results and any additional services that may be included in the package.

What happens if the results of a hair-based DNA test are inconclusive?

In some cases, a DNA test may not yield conclusive results due to factors such as poor sample quality or contamination. If this is the case, the lab can either retest your sample or recommend additional tests that may help provide more clarity. Additionally, some labs may offer additional services such as genetic counseling to help you better understand your results.

Are hair-based DNA tests only for paternity testing?

Hair-based DNA tests can be used for a variety of purposes, from determining paternity to finding out more about your ancestry and family history. Labs can also use the results of a hair-based DNA test to look for inherited conditions or diseases that may be present in your genes.

Q: Can you do a DNA test with hair?

A: Yes, it is possible to do a DNA test with hair.

Q: How does a hair DNA test work?

A: A hair DNA test works by analyzing the DNA present in the hair follicle.

Q: What is a hair follicle?

A: A hair follicle is the part of the skin from which a hair grows. It contains the DNA that can be used for testing.

Q: What is a DNA sample?

A: A DNA sample is a biological material, such as a hair follicle or a cheek swab, that contains the individual’s DNA.

Q: Do I need to collect the hair sample myself?

A: You can collect the hair sample yourself using a sample collection kit, or you can go to a professional who will collect it for you.

Q: Is a hair DNA test legally admissible?

A: Yes, a hair DNA test can be legally admissible if the proper chain of custody is maintained throughout the testing process.

Q: How accurate is a hair DNA test?

A: Hair DNA testing can be highly accurate, with a success rate of over 99% for paternity testing.

Q: Can a hair DNA test determine paternity?

A: Yes, a hair DNA test can determine paternity by comparing the DNA of the alleged father with the DNA from the hair sample.

Q: Can moisture affect the viability of the hair sample?

A: Yes, moisture can affect the viability of the hair sample. It is important to ensure that the sample is collected and stored properly.

Q: Can I use hair strands instead of follicles for a DNA test?

A: No, hair strands alone are not sufficient for a DNA test. The follicles must have a root for accurate analysis.
