Authors: Laura Elena Paviliu, Andreea Dimitriu
Hair loss is a common and distressing clinical complaint in the dermatology daily practice. Standard methods used to diagnose hair disorders are clinical inspection, pattern of hair loss, pull test, trichogram, biopsy.
Trichoscopy refers to the dermoscopy of the hair and scalp disorders. It is a fast, novel, non-invasive technique that improves diagnostic accuracy and follow-up of hair and scalp disorders. The technique can be performed with both handheld dermatoscope and digital videodermatoscopy system.
The magnified image is useful for the assessment of the structures that are not visible to the naked eye. Structures which may be visualized by trichoscopy include hair shafts, hair follicle openings, the perifollicular epidermis and the cutaneous microvessels. This will help dermatologists to distinguish between unique trichoscopic features, and allow them to provide more accurate diagnoses and treatments for the patients.
Trichoscopy can easly differentiate scarring and non scarring allopecia and reduce the need for unnecessary scalp biopsies. When a biopsy is still needed it is helpful in choosing an ideal biopsy site. Moreover, trichoscopy is a valuable tool for evaluating the treatment response and prognosis at each follow-up.
Great dermatologists said that the dermatoscopy can be considered “the stethoscope“ or “the third eye“ of an dermatologist.
