Ducray Dermatological Laboratories CHRONOSTIM Day/Night Anti-Hair Loss Treatment is one of the latest additions to Ducray"s hair loss research. When hair loss increases, not only does one need to slow down this process but it is also necessary to stimulate the growth of new hair. To act effectively Ducray Laboratories have developped CHRONOSTIM.To slow down hair loss: CHRONOSTIM "Morning"contains Sabal Serrulata enriched in Lauric Acid. It showed its effectiveness to inhibit the enzymatic activity of one of the main causes of hair loss (the enzymatic activity ratio responsible for hair loss is higher in the morning). The formula also contains Tocopherol Nicotinate, which will facilitate the penetration of the active ingredients.To support hair growth: CHRONOSTIM "Evening" contains extract of Ruscus rich in Néoruscine to support the production of VEGF (Vascular Endothelial Growth Factor), essential factor to hair growth, recently identified. The GP4G, powerful stimulating agent of cellular metabolisms, integrated in the formula, will restart the exchanges on the level of the dermic papilla, thus supporting a resumption of hair growth. In the evening, one notes an increase in the cellular activity which allows hair to grow.As a supplement to this product we advice you to use Ducray ANAPHASE stimulating cream shampoo
