How many times and how much minoxidil to apply

Minoxidil is a popular product in order to regrow hair or even to grow a beard.

There is however a lot of information and misinformation circulating about how much minoxidil to apply and how many times to apply minoxidil.

That’s why I want to review what the current research has to say about how much minoxidil to apply and how “many times should I apply minoxidil to my beard”.


How many times should I apply minoxidil

Minoxidil uptake is about 50% after an hour and 75% after 4 hours.”[1]

How many times a day should I use minoxidil?

Based on the above research, I would suggest applying topical minoxidil two times daily. Although, people have also reported positive results with just applying minoxidil once. This does not mean that applying minoxidil only one time each day is optimal, however.

It is important that you know how to apply topical minoxidil the right way in order to optimize its efficiency.

To summarize, based on the current research, applying minoxidil two times a day is the most optimal frequency for efficiency.[2]

How much minoxidil to apply

One should apply about 1ml of topical minoxidil foam or liquid each time one applies minoxidil. This should be done twice daily.

That’s roughly equal to 1/2 cap of minoxidil foam or 25 drops of liquid minoxidil.

This means that if you apply minoxidil twice daily, you would use about 2ml total.

For reference, one bottle of minoxidil should last for about a month. Give or take a few days.

Where to apply minoxidil

One should aim to apply just enough minoxidil like Rogaine to cover the desired area. For beard growth, this means possibly applying minoxidil to the cheeks, chin, underneath the chin and the mustache, depending on where you are lacking beard growth.


How long should I keep the minoxidil on my face

How long does it take for minoxidil to dry

As noted above, minoxidil uptake is about 75% after 4 hours.

To make the most out of it, I would recommend keeping the topical minoxidil on your face for at least 4 hours, and 6 hours if possible for optimal results.

It’s not an exact science, but keeping the minoxidil on your face for at least an hour is the bare minimum to see decent results. Washing and rinsing off the minoxidil immediately after applying it to your face will lead to virtually no results.

Of course, knowing how to apply minoxidil is essential to produce the best results, and to guarantee your safety.
