Abstract

Trichoscopy is the technique that allows to visualize perifollicular epidermis and blood vessels, without distinction of the corporal region, hair fibers and follicular openings, by means of a dermatoscope or videodermatoscope. A bibliographic review was carried out in Medline, PubMed and SciELO databases between January and April 2021, with the aim of understanding the main aspects of the technique and the main trichoscopic findings in healthy patients and in those with diagnosis of hair diseases. The search terms included “trichoscopy”, “dermatoscopy”, “hair” and “alopecia”, in Spanish and in English; the DeCS-Descriptors in Health Sciences thesaurus was used for the delimitation. The search revealed 70 articles of which only 39 met the inclusion criteria. 83 % of the papers belonged to technique knowledge and trichoscopic findings associated to hair diseases. 17 % stated current concepts of the entities that affect these areas. There were described basic elements of trichoscopy and trichoscopic findings in healthy patients and in those suffering any regional condition. When analyzing the behavior of the articles and their representativeness in scientific journals, it was found that International Journal of Trichology and Skin Appendage Disorders, were those publications that contributed with more studies. The role of trichoscopy is unquestionable in hair and scalp pathologies. Knowledge of the technique and the trichoscopic patterns described and adaptable to specific entities are important to carry out an adequate analysis and follow-up of cases.
