Resumen en inglés A topical cosmetic formulation is currently commercially available for the treatment of Brittle Nail Syndrome, a formulation made up of Equisetum arvense, Methyl sulfonyl methane and Hydroxypropyl chitosan. However, the habit of applying nail polish hinders the adherence to treatments that preclude their use. Objective: To propose a scheme that alternates the use of the formulation fi ve times a week, with nail polish. Methods: A clinical, single-blind, crossover controlled intraindividual trial was carried out with 38 female patients. The patients’ hands were randomized into two groups (A and B). Results: From weeks 1 to 8, and from Sunday to Thursday, Group A applied the formulation A while Group B did not undergo treatment. In weeks 9 to 16, Group A suspended the application of the formulation, while Group B began treatment. From Thursday to Sunday Groups A and B had their nails painted. A common nail polish was standardized for both groups. A quantitative score was used to evaluate outcomes and observe the percentage of patients who had improvements greater than 50% and 75%. Conclusions: The formulation was more effective in controlling the signs of the syndrome when the nail polish was used in the intervals of the applications. The present study allowed the authors to propose a treatment regimen using the formulation 5 times a week, alternating with the practice of painting the nails
