trikoskopia

Trikoscopy is a diagnostic method used in trichology, the study of hair and scalp disorders. It involves the magnified examination of the hair and scalp to identify abnormalities that might not be visible to the naked eye. This technique allows for a more detailed assessment of hair density, shaft structure, scalp conditions, and the presence of any parasites or fungal infections.

The examination typically uses a handheld or mounted magnifying device, often a dermatoscope or a specialized video microscope. This allows the trichologist to observe the hair follicles, the cuticle of the hair shaft, and the surface of the scalp with significant magnification, often ranging from 10x to 200x or more. The acquired images or videos can be documented for comparison over time or to explain findings to the patient.

Trikoscopy can aid in the diagnosis of various conditions. For instance, it can help differentiate between different types of alopecia, such as androgenetic alopecia or alopecia areata, by observing characteristic patterns of hair loss and follicle miniaturization. It is also useful in identifying scalp issues like psoriasis, seborrheic dermatitis, or infections such as tinea capitis. Furthermore, trikoscopy can detect structural abnormalities of the hair shaft, such as trichorrhexis nodosa or pili torti, which can lead to breakage. The insights gained from trikoscopy guide the selection of appropriate treatment strategies for hair and scalp concerns.
