A TrichoScan, also known as a photo-trichogram, combines a microscope with software, using IT to determine the state of a patient's hair. Whereas a trichogram requires hairs to be physically extracted, all that a TrichoScan requires is for the area to be examined (ca. 16 - 20 mm) to be shaven. This shaven part of the scalp is then coloured, dermatoscopically photographed and analysed. The digital photo creates a video image which is then assessed by the software, determining hair density. When doing a TrichoScan to determine the state of a patient's hair roots, the shaven patch of the scalp is again coloured and photographed three days later. If the hairs are in their resting or falling-out phase, they will not grow during this period, thereby providing the doctor with important indications of the type of hair loss. Clear advantages of a TrichoScan: a TrichoScan is painless and the result can be archived, allowing changes to be tracked. In addition, Dr. Feriduni and his patient can both view the state of the latter's hair on the computer monitor, exactly tracking the results of the therapy.
