Trichoscopy involves placing a head on the patient’s scalp, which displays the image on the computer screen. The equipment allows you to view the skin up to 100x magnification and to take and save photos from the course of the examination, which significantly facilitates diagnostics. Maximum magnification is helpful, but most of the time, the skin is viewed by positioning the diagnostic tool differently.
Both 20 times and 70 times magnification can be used. In the first phase of the test, they are performed without the use of additional specifics. The doctor can then apply an immersion fluid to the skin that has a specific refractive index and allows you to slightly change the resolving power of the equipment used during the test. It is used depending on the initial suspicions about the disease and the condition of the scalp.
During the examination, special attention is paid to lesions, but using a dermatoscope you can also determine the condition and amount of hair and hair follicles, and also carefully look at the growth phases of individual hairs – the doctor is able to assess which of them are currently in the growth phase , downtime, and which are in the dying off phase and determine whether the observed state of affairs is within the normal range. The examination usually takes 20 to 30 minutes.
