After you perform a trichoscopy examination you have 2 options:

  1. Send/ upload to TrichoLAB (it costs credits - the amount depends on the procedure)

  2. Analyze it by yourself - you need a special module for that called Local Processing (Space) or TrichoScale AI (Suite)

Below is a view of the panel when performing a trichoscopy examination. If you want to analyze your examination you have to click "Processing"

When you select processing, your images will automatically be analyzed. After analyzing all photos (it depends on your procedure, settings and software version: Space/ Suite) it will be possible to download a report with statistics. As the analysis is performed by artificial intelligence, we recommend manual correction. For this purpose you will need 2 options:

1. Adding hair or modifying existing ones

2. Removal of incorrectly selected hair

Please follow these steps to prepare statistics of your examination:

1️⃣ Enter the examination that you want to analyze and click the "processing" button.

2️⃣ Let the photo analyze itself. It will take a few seconds.


3️⃣ Correct photo.

As the analysis is performed by artificial intelligence, we recommend manual correction. For this purpose you will need 2 options:

There is a slider in the upper corner. You can use it to zoom in on the photo (if you don't have any hair selected - instructions below) you can zoom in/out as well with Mouse Wheel.

🔷 Adding hair or modifying existing ones

  • Locate a hair that is not marked.

  • Use the left mouse button to create it - draw a line in this place (currently selected hair is highlighted in yellow)

  • Use the Mouse Wheel - spinning it up or down - to increase or decrease the diameter of the hair. Match the width of the marked line to the width of the hair in the photo.

  • By holding the hair with the right mouse button you can bend it - match the shape of your line to the original hair - it will be easier for you to adjust the width.

  • You can modify existing hair by selecting it.

  • Note that with each modification (adding, widening, narrowing, deleting) the statistics on the right side change.

🔷 Removal of incorrectly selected hair

  • Choose hair, click on it and press the "Delete" button on your keyboard.

🔷 With each modification: adding, widening, narrowing, deleting hair the statistics on the right side change. You have as many columns with statistics as many areas you select (the default trichoscopy is 3 areas, which is why you see 3 tabs: frontal, temporal and occipital) After analyzing all the images from a given area, you will have the statistics of that area.

🔷At the bottom part of your panel you have 4 types of view. You can switch to any of them, depending on your needs:

🔹Basic view (default)

🔹Terminal/ Velus - divides hair into two types (yellow- terminal and orange- -vellus) On a chart at the right side of your panel you can adjust hair thickness by swiping red dot. You can change your Thickness chart into Pie Chart.

🔹Single Hair View - each hair shaft has different color.

🔹Follicular Units - each follicular unit is marked in a circle, additionally you have a number on them, that tells you how numerous this follicular unit is.

4️⃣ Do the same with all photos

🔷 AGASI - AGA Severity Index (Local Processing feature)

As this index is a comparison of the occipital and frontal areas, you have to shoot both these areas to receive it. In settings (gear icon - right-up corner) you can change thresholds indicators (for personalized results) - this option is available only with Local Processing

5️⃣ Download your report

To download the report you have to have all the photos analyzed.

You can download the report in pdf format. When you click "generate report", a window will appear with the possibility of adding comments - prescriptions for the patient, observations and anything else you need / want to have in your report.

There is also a possibility to export your file to .csv
