Objective. Increase the effectiveness of complex therapy for patients with telogen alopecia with simultaneous use of the drug «Volvit tablets» (biotin 5 mg) inside and «Volvit intensive care shampoo» with biotin externally. Materials and methods. Patients with telogen alopecia, aged 22 to 40 years, who had complaints and a history of the disease (time of onset of increased hair loss, connection of baldness with stress, medication, viral infection, etc.) were under observation.

Consultations with an endocrinologist, psychotherapist, hematologist and other specialists were scheduled. Results and discussion. On the basis of the analysis of literary sources and own clinical and laboratory studies, a complex therapy of diffuse telogen alopecia was developed with the simultaneous appointment of the drug «Volvit tablets» (biotin 5 mg) and «Volvit intensive care shampoo» with biotin, which has a dual effect (treatment from the inside and cosmetic care behind the hair and scalp from the outside). The diagnosis of diffuse telogen alopecia was established on the basis of the clinical picture of the disease and laboratory diagnostic data. Clinical symptoms in patients with telogen alopecia are manifested by uniform, intense hair loss over the entire head, which is noticed after washing the head and combing, when a lot of hair that has fallen out remains. After examining the patient, an individual treatment plan was drawn up, taking into account the identified factors of the disease and accompanying pathology. One of the most common causes of hair loss is an insufficient amount of biotin in the body, and the causes of a decrease in the amount of biotin in the body are stressful situations, an unbalanced diet with an insufficient amount of biotin in products, intestinal dysbacteriosis, diseases of internal organs, disorders of the endocrine system, transferred viral diseases, taking antibiotics and other. Taking into account the above, in the complex therapy of patients with diffuse telogen alopecia, the drug «Volvit tablets» (biotin 5 mg) inside 5 mg once a day and «Volvit intensive care shampoo with biotin» were prescribed at the same time, as a result, good therapeutic results were achieved.
