🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine combines two active ingredients with complementary mechanisms. Minoxidil is a vasodilator that opens potassium channels in the smooth muscle of blood vessels, leading to relaxation and widening of the blood vessels in the scalp. This increases blood flow, oxygen, and nutrient delivery to the hair follicles. Minoxidil also prolongs the anagen (growth) phase of the hair cycle and shortens the telogen (resting) phase, which increases the size and number of hair follicles. Aminexil works by inhibiting the formation of collagen around the hair follicle, reducing perifollicular fibrosis. This fibrosis is a process where collagen fibers stiffen and compress the follicle, leading to reduced blood supply and premature hair shedding. By preventing this stiffening, aminexil helps maintain a healthy environment for hair growth and prolongs the life of the hair follicle.
