espanolLas alopecias cicatrizales se consideran un grupo de enfermedades del pelo que ha tenido en la actualidad un gran campo de investigacion. Existen multiples herramientas para realizar un algoritmo diagnostico, entre ellas la tricoscopia, el estudio histopatologico o la microscopia confocal, aunque algunas tienen desventajas en cuanto a costo o son invasivas como la biopsia; por esa razon, la tricoscopia ha resultado un metodo accesible, de bajo costo, no invasivo y puede efectuarse al momento de la consulta para establecer un diagnostico mas especifico e instituir un tratamiento oportuno. La importancia de conocer e identificar los patrones tricologicos de forma temprana para las alopecias, en especial las alopecias cicatrizales, radica en identificar los signos que eviten la progresion de la enfermedad, sobre todo en etapas reversibles. EnglishScarring alopecia is considered a group of hair diseases for which there has currently been a large field of research. There are multiple tools that can be used when performing a diagnostic algorithm, such as trichoscopy, histopathological study, and confocal microscopy, however some of these have cost disadvantages, in the case of biopsy taking, as it is an invasive method, therefore, trichoscopy has been an accessible, inexpensive, non-invasive method that can be performed at the time of the consultation, in order to obtain a more specific diagnosis and be able to provide timely treatment. The importance of knowing and identifying trichological patterns early for alopecia, specifically scarring alopecia, lies in being able to identify data that can prevent the progression of the disease, especially in reversible stages.
