Discover Aminexil, a breakthrough patented molecule developed by L'Oréal's advanced research, specifically designed to effectively combat hair loss. This innovative synthetic molecule, structurally similar to minoxidil, offers a key advantage: unlike minoxidil, Aminexil from Vichy Canada is not a vasodilator, which can come with severe adverse effects. Aminexil acts by softening the collagen around the hair bulb to allow the hair to feel less compressed, and thereby decrease hair loss. 

The key difference lies in the mechanism of action. One is a vasodilator, which can come with severe adverse effects. Aminexil, on the other hand, acts by softening the collagen around the hair bulb to allow the hair to feel less compressed, and thereby decrease hair loss.
