Background/Aims: Hair exerts protection, sensory functions, thermoregulation, and sexual attractiveness. Hair loss (alopecia) is caused by several diseases, drug intake, hormone imbalance, stress, and infections (Malassesia furfur). Drugs usually used in alopecia produce irreversible systemic and local side effects. An association of extracts of Coffea arabica and Larrea divaricata (ECOHAIR®) is successfully being commercialized in Argentina for hair growth. The aim of this study was to provide scientific support for the efficacy and innocuousness of ECOHAIR® in patients with noncicatricial alopecia during a 3-month treatment. Methods: The efficacy was determined through the assessment of an increase in hair volume, improvement in hair looks, growth of new hair, and a decrease in hair loss by the test of hair count and hair traction. The capacity to decrease the amount of dandruff was also evaluated as well as the adverse local effects caused by the treatment. Results: ECOHAIR® spray improved the overall hair volume and appearance; it increased its thickness, induced hair growth, and decreased hair loss. Besides, no adverse local reactions were observed upon treatment with the product. Conclusion: This study provides scientific support for the clinical use of ECOHAIR® as a treatment to be used in noncicatricial alopecia.
