Fred, I'm from Brussels too. Every pharmacy in Belgium sells basically the same sprayers. They are awful, unpractical and they spread to much liquid at a time (at least 0,2 ml per spray). That's why they are messy. In contrast, the Revivogen (or minoxidil Regenepure) sprayers are much smaller...
for Revivogen users...
If you are a Revivogen user, you can put your minoxidil in a used Revivogen bottle.
Every pack with 3 bottles of Revivogen comes with a sprayer. Each spray sprays 1 ml of solution.
Applying minoxidil with a sprayer is definitely the more convenient way to do it.
If are...
