Despite the variety of etiological factors that can cause hair loss, these types of alopecies share a common characteristic: cessation of hair growth during the anagen phase. The variety of underlying causes of hair loss in these forms of alopecia complicates both therapy choice and clinical management. In this article the authors share their own clinical experience in treating such patients. Modern drugs and topical agents allow for maximum results with the absence of side effects. Treatment efficacy was assessed by clinical tests (visual examination and pull test assessment), as well as objective diagnostic methods, including trichoscopy using TrichoSciencePro software, trichogram and phototrichogram. Two clinical cases with treatment of patients with telogen effluvium are presented.</p></abstract><trans-abstract xml:lang="ru"><p>Понятие «диффузная потеря волос» подразумевает нерубцовую потерю волос, вызванную различными причинами. Несмотря на разнообразие этиологических факторов, которые могут вызвать выпадение волос, данные алопеции объединяет единый признак — прекращение роста волос в стадию анагена. Многообразие причин потери волос при данных формах алопеции влечет сложности в выборе терапии и определении тактики ведения пациентов. В представленной статье авторы делятся собственным клиническим опытом лечения таких пациентов. Современные лекарственные препараты и наружные средства позволяют добиться максимального результата при отсутствии побочных эффектов. Эффективность терапии оценивалась клиническими исследованиями (визуальный осмотр и оценка пулл-теста), а также объективными методами диагностики, такими как трихоскопия с помощью программы TrichoSciencePro, трихограмма и фототрихограмма. Представлены два клинических случая терапии пациентов с телогеновым выпадением волос.</p></trans-abstract><kwd-group xml:lang="en"><kwd>diffuse alopecia</kwd><kwd>telogen effluvium</kwd><kwd>alopecia</kwd><kwd>trichoscopy</kwd><kwd>trichogram</kwd><kwd>alopecia treatment</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>алопеция диффузная</kwd><kwd>телогеновая алопеция</kwd><kwd>облысение</kwd><kwd>трихоскопия</kwd><kwd>трихограмма</kwd><kwd>лечение алопеции</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Alcoy LLC</funding-statement><funding-statement xml:lang="ru">ООО «Алкой»</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sinclair R.
