Nowadays, various forms of minoxidil are available on the market in different concentrations. It can deliver visible results within one week. However, individuals using minoxidil should be aware of both the risks and benefits of this medication.
How Does Minoxidil Work in the Body?
Minoxidil is a vasodilator that acts through three primary mechanisms:
- Opening Potassium Channels: Minoxidil opens ATP-sensitive potassium channels in vascular smooth muscle, leading to relaxation of these muscles.
- Vasodilation: It relaxes blood vessels, increasing blood flow to the scalp and delivering more nutrients and oxygen to hair follicles.
- Prolonging the Anagen Phase: Minoxidil promotes the transition of hair follicles from the telogen (resting) phase to the anagen (growth) phase, resulting in increased hair regrowth.
What are the Benefits of Minoxidil?
- Hair Regrowth: Minoxidil effectively promotes hair regrowth in individuals with androgenetic alopecia (male and female pattern baldness). It is often the first-line treatment for this condition.
- Increased Hair Thickness: Many users report not only regrowth but also thicker hair strands.
- Topical Use: Minoxidil is available in topical formulations (liquid or foam), allowing for localized application with fewer systemic effects compared to oral medications.
What are the Risks of Minoxidil?
- Skin Irritation: Common side effects include itching, redness, or flaking at the application site.
- Unwanted Facial Hair Growth: Some users may experience unwanted hair growth in areas other than the scalp.
- Rapid Heart Rate (Tachycardia): In rare cases, minoxidil can cause an increased heart rate, particularly if absorbed systemically.
- Hypotension: As a vasodilator, minoxidil can lower blood pressure, leading to dizziness or fainting in some individuals.
- Weight Gain: Fluid retention and weight gain may occur, necessitating monitoring for signs of heart failure.
What are the brands available?
It is recommended to consult a healthcare professional before starting treatment, especially if you have underlying health conditions or are taking other medications.
