A trichogram is a procedure that helps you monitor the anagen and telogen ratio on your patient's scalp. The first photo is taken right after shaving, the next after about two days.
It is important to shave the hair to a height of about 0.4-0.6 mm. Make sure that all the hair in the area where you are taking the picture is shaved and of the same length.
The examination consists of two parts:
1. Just after shaving
2. After regrowth (about 48h)
Total photos number: 4
Just after shaving: 2 (global and micro images)
After regrowth: 2 (global and micro images)
🔷Preparation - hair clipping
During the first visit, you will shave the patient.
The shaved area should not be smaller than 2cm x 1,5cm (big enough to place the camera lens in the shaved area)
We recommend having an electric razor with an adjustable shaving length. The length you shave is less than 1 mm. Shaved hair length is about 0.4-0.6 mm.
The hair should be cut evenly.
Hair that is too long will be impossible to measure - its ends will go beyond the edge of the image.
Too short hair may not be detected by the software - as a result, you may have problems with finding the Virtual Tattoo.
Shaving the test area
To clean the patient's scalp you can use adhesive tape - it collects the cutted pieces of hair well and does not leave material fibers on the scalp.
📌Important: hair must be contrasting (i.e., dark hair against light skin.) If your patient has light - blond or gray hair, we recommend dyeing it. If the hair is not clearly visible, the system will not detect it, so Virtual Tattoo will not work on after the regrowth photo.
Hair dying
🟥The software highlights in red hairs that are significantly longer than others. Then move the camera a bit to a different test area or shave the hair again - be careful not to shave too much.
🟨 In yellow are marked hairs that go beyond the measurement area (edge of the photo)
🔷 After regrow
After about 48 hours finish the examination. (It doesn't have to be exactly 48h, it can be a few hours earlier or later - important: the gap cannot be too long.) If the hair is too long, it will cover each other, and a large part of the hair will go beyond the test area - making it impossible to measure.
Our software will help you position the camera well and find the same place.
In the upper right corner of Live View you have 2 lines (they look like a clock.) They tell you the direction of the hair. Try to position the camera so that the arrows overlap (then they will change from red and blue to green) - this means that the direction of the hair now is the same as in the first picture.
With the help of Virtual TattooNow find the same place as in the first picture. Follow the red and blue circles. Wait until the green circles fill up completely and the photo will be taken automatically.
Then you can save and upload to TrichoLAB - then within 7 days we will prepare a report with statistics for you or you can save only and analyze it locally (If you have Local Processing)
🔷 Results
You will get charts divided into anagen and telogen about hair thickness and grow rate, and the rest of the hair statistics shown in the image below.
