Can I Use Minoxidil More Than Twice A Day

In every bottle of minoxidil, you can see the recommended dosage is 2ml a day, 1ml in the morning and 1ml in the evening. Even if your doctor prescribes you minoxidil, he will recommend you to follow this same guideline.

The reason doctor and minoxidil companies tell you to use it twice in a day is the lifespan of minoxidil, which is 20 to 22 hours. That means, if you apply minoxidil in your scalp or beard, it will work for 20 to 22 hours.

It is impossible to know if it will work for you 20 hours or 22 hours, but let’s consider the minimum which is 20 hours, which means if you use it every 20 hours, it will still be effective for you.

Based on this, sometimes you can even use minoxidil only once a day, twice is not even required. Then why would you want to use it more than twice? It’s a medicine and consider it’s as a medicine.

If someone takes a double dose of blood pressure medicine or diabetic medication, what will happen? They will suffer severe side effects and may even die.

So, don’t take more than the recommended dosage of any medicine.
