I started using this solution 15 days ago(m20) and applying twice a day has become too much of a hassle in general and more importantly with cost of this solution is significantly higher than normal minoxidil 5%.
Just need an advice whether i could apply it once a day one hour before sleep???
You can apply it once a day, one hour before sleep. Consistency is key, so make sure to apply it regularly. Once a day should still be effective, especially if it helps you stick with it.
