You will receive an email from DA Labs informing you that your results are ready. Once notified, you can log into your DA Labs account to find out if Minoxidil will work for you. 

If you are a responder, you can confidently proceed with Minoxidil treatments.

Though being a non-responder can initially be disappointing, you will save time, money, and be able to focus your efforts on other hair loss solutions. 


Hair samples MUST be collected and shipped on the same day.

Ensure your hair sample is not exposed to temperatures above 111 degrees Fahrenheit or 44 degrees Celsius. A temperature indicator is attached to the hair collection card. 

If the laboratory is unable to process your sample, you will be notified by email and provided with one free replacement kit to send in a new sample.

The MRT report does not diagnose health conditions or provide medical advice. Consult with a healthcare professional before making major lifestyle changes or if you have concerns about your results.

MRT is a laboratory-developed test. In clinical trials, MRT had a 95.9% accuracy in determining non-responders to Minoxidil-based treatments. 100% of people without the enzyme were correctly diagnosed, with only a 25% chance of a false negative.
