hey n1kk6,
I swapped out my 5% for Xandrox 15 a few months back and can only tell you the following: Way too early to determine true results, but I've seen lots of what appear to be vellus hairs (where my hairline used to be). From my temple recessions, down and straight across. Whether or not these will manifest (sorry aout the terminoligy) remains to be seen. I have recently (last 2 weeks) noticed some terminal hairs in the hairline area also, but nothing drastic (10-20 maybe)..
Now on a down note.... I apply at night (usually around 9-10PM) and in the morning, my head is still sticky. I'm guessing that most of the minoxidil is being absorbed, but it does make for some messy pillows and just a low comfort level at times.
Sorry I cound't be more help, but honestly, I think I'm going to make the 12.5 switch as soon as it's available myself. I feel as though I've made gains, but would like a little more user-friendly solution.
