What is Minoxidil?
Minoxidil is a vasodilator medication originally developed to treat high blood pressure. However, during clinical trials, researchers noticed an unexpected side effect: hair regrowth. This serendipitous discovery led to its topical formulation, now widely used to combat hair loss.
Today, minoxidil is FDA-approved for treating androgenetic alopecia (male and female pattern baldness). It is available over-the-counter in various strengths, including 2% and 5% solutions and foams.
How Minoxidil Works
Minoxidil works by widening blood vessels and opening potassium channels. This process improves blood flow to hair follicles, stimulating them to enter the anagen (growth) phase of the hair cycle.
Key Mechanisms of Action:
- Vasodilation: Enhances nutrient and oxygen delivery to hair follicles.
- Follicle Stimulation: Encourages dormant follicles to re-enter the growth phase.
- Prolonged Anagen Phase: Keeps hair in the growth phase longer, resulting in thicker strands.
Here’s a summary table of minoxidil’s key mechanisms:
| Mechanism | Effect |
|---|---|
| Vasodilation | Blood vessel widening improves nutrient and oxygen delivery to follicles |
| Potassium Channel Opening | Enhances blood flow to hair follicles |
| Follicle Activation | Stimulates dormant follicles to enter growth phase |
| Growth Phase Extension | Maintains longer anagen phase for thicker hair growth |
Types of Minoxidil Products
Minoxidil is available in several formulations, each catering to different preferences and scalp sensitivities.
1. Topical Solution

2. Foam

3. Oral Minoxidil
