I've ordered Xandrox 5% and Spectral DNC to use in the morning and evening (in that order). However, I read somewhere that new users should test their reaction by starting off with 2% minoxidil first. Not sure if this would just be a waste of time. Any opinions?
The 2% and 5% versions of Rogaine are essentially the same thing, because they both turn into the same thing (saturated solutions of minoxidil in propylene glycol) when you apply them to your scalp. Only the quantities of that saturated solution are different. So if you apply a smaller quantity of the 5% solution, you'll end up the same as if you were to apply a larger quantity of the 2% solution. Understand what I'm saying?
