Trichoscan hair diagnosis is a digitalized analysis that measures hair density and the proportion that is in the anagen or telogen growth phase, in the fastest, most accurate and painless way.

This examination allows us to quantify the degree of alopecia and, if a periodic observation is carried out (semi-annual or annual), to assess its evolution.

In addition, it allows us to objectiveize the results of a treatment, such as the application of one of our anti-hair loss formulas.

    Trichoscan Diagnosis

    Trichoscan hair diagnosis allows the study of hair density and the proportion of follicles in the anagen or telogen phase in vivo—that is, without the need to extract hair samples from the patient. This alone is a great advantage over other more invasive techniques, such as classic trichograms, which required the extraction of 50 to 100 hairs.

    The complete Trichoscan hair study is carried out in two sessions:

    • During the first, the area to be explored is chosen – a surface 2 centimeters in diameter, which presents the problem, but which is not visible with the patient’s usual hairstyle. She shaves and dyes her hair, to make sure she also captures and counts the thinnest or lightest hair.
    • In the second session, a 20x photograph of the area is taken and the results are analyzed. This session is performed three days after the first to distinguish hair that has grown (in anagen phase) from hair that has not —in telogen.


    The photograph of the area is used to count the number of hairs in that area – hair density – and classify them based on the growth phase they are in – anagen/telogen ratio. These two parameters are the keys to knowing the stage of alopecia.

    In addition, the Trichoscan study incorporates an image archiving system, which allows them to be compared in successive scans. In this way, the evolution of alopecia can be objectively analyzed – change in density and anagen/telogen proportion – or the result of the treatment – increase or not in density and anagen hair – that is being carried out. For example, the application of an anti-hair loss formula.

    Thanks to the Trichoscan study, you will have precise and objective measurements, which will allow the dermatologist to advise you on a treatment and maintain it or change it depending on the results.
