Minoxidil 2.5mg used as a treatment for severe refractory hypertension due to its potent vasodilatory qualities. It has a relaxant effect on vascular smooth muscle through the opening of ATP sensitive potassium channels
1. Vasodilation: Minoxidil tablets work as a vasodilator, meaning they widen blood vessels. This dilation increases blood flow to various parts of the body, including the scalp.
2. Increased Blood Flow to Hair Follicles: By increasing blood flow to the scalp, minoxidil tablets improve the delivery of oxygen, nutrients, and other growth-promoting substances to the hair follicles.
3. Prolonged Anagen Phase: The hair growth cycle consists of three phases: anagen (growth phase), catagen (transitional phase), and telogen (resting phase). Minoxidil may lengthen the anagen phase, allowing hair to grow longer and thicker before entering the shedding phase.
4. Stimulation of Hair Follicles: Minoxidil may also directly stimulate hair follicles, encouraging them to produce thicker and more robust hairs.
