Most often, 20x and 70x magnifications are used. Trichoscopy assesses hair shafts, hair follicle openings and the surrounding skin. This method allows to assess the above elements without the need for hair sampling (non-invasive method).

During the procedure, a camera is used to capture the image of the hair and scalp in three areas of the head: the frontal, temporal and occipital areas. In each of these locations, the investigator takes 4 pictures. Depending on conditions and clinical suspicions, the procedure is performed using a liquid or without it (the "dry" method).

Trichoscopy allows to differentiate various types of hair loss, especially androgenetic alopecia with telogen effluvium, and allows to diagnose dystrophic, residual and broken hair. This method also allows to assess the activity of such inflammatory conditions as lichen planopilaris (LPP) and discoid lupus erythematosus (DLE).

Trichoscopy allows to objectively assess the effectiveness of therapy, which in many cases is very important for the patient due to the psychosomatic aspect of many scalp dermatoses.
