How It Works

The Fagron TrichoTest™ is a simple test to take and administer, but under the surface it’s backed with science, research and innovative analysis that can identify which hair loss treatments are most likely to provide the best results for you.

Fagron TrichoTest™ - Treatments

Taking the test is easy and can be done by anyone, here is a short step-by-step guide that explains the process and how it works:

The process begins with a simple saliva (buccal) swab taken in clinic or at home* with a professional, to obtain a sample of your DNA.

You then will need to complete an online questionnaire about your lifestyle factors. This will take around 30 minutes and will include questions about your age, height, weight and any medical conditions you may have.

The swab is returned to the Fagron UK hub before being shipped to our state-of-the-art laboratory in Barcelona. Our laboratory uses the most advanced technology available for genomics analysis.

Using highly specialised TaqMan OpenArray technology, DNA is extracted from your saliva swab and the gene mutations relevant to hair loss are identified and analysed together with the information provided by your online lifestyle questionnaire.

When the analysis is complete, a digital report is generated and sent securely to your hair loss specialist or trichologist for them to review. The report outlines the gene variations that we analysed alongside any identified mutations. This is then followed by the subsequent recommended hair loss treatment options for these, which allows for a personalised treatment plan to be created by your specialist.
