Is 5% minoxidil more effective than 2% minoxidil?
Yes, it is much more effective. Minoxidil is dose-dependent. The higher the dose of Minoxidil, the better the results. Using 5% Minoxidil does not give you faster results, but will cause the regrowth of more hair and thicker hair. The 5% Minoxidil solution can cause more skin irritation than the 2% solution.
