What is a digital trichoscopy?

Trichoscopy is a non-invasive procedure to diagnose hair problems. A biologist takes pictures of the scalp and hair using video dermoscopy.
These pictures are then analyzed by an artificial intelligence software, which will measure a number of parameters.
The final diagnosis is then established on this information by a doctor specializing in hair loss problems.


What is a trichoscopy used for?

A trichoscopy is used to:

determine the cause of hair loss
to measure the impact of a hair loss treatment

Which factors are measured?

A trichoscopy measures seven factors:

  • average number of hairs
  • average thickness of the hair shaft
  • number of fine, medium and thick hairs
  • number of follicular units (single, double, triple and more)
  • number of empty hair follicles/yellow spots
  • cumulative hair thickness
  • number of follicular units

How is the examination done?

The examination is performed by a biologist who specializes in videodermoscopy, a skin imaging technique that allows the areas to be magnified up to 70 times. He takes several pictures of the scalp and hair in the three main areas; the frontal, temporal and occipital areas.

The pictures are then analyzed using computerized recognition and artificial intelligence algorithms that accurately measure the various factors.

The final diagnosis is checked by a doctor specializing in hair loss problems.

Good to know:
Trichoscopy is a non-invasive examination.
The examination takes between 20 and 30 minutes.
Please do not wear any covering powder on the day of the examination, as it may affect the results.
The biologist will ask you some questions about your hair loss during the examination. Your answers will contribute to the final diagnosis.
The results will be interpreted and explained during a consultation with your physician or with a CMCC physician. The trichoscopy report will be given to you and will serve as a reference to evaluate the effectiveness of the treatment.
2 to 3 weeks are needed to see results.
