I can offer some info but it's all theory and not real science. Responding because you PM'd and seem to need help.
I've read that it's better to take finasteride in the morning because that's when hormone levels are at their highest. Not sure how true that is.
I assume you are using minoxidil foam and not liquid? If so, you should probably use the foam first, and K&B second.
Why minoxidil foam before K&B?
Minoxidil foam dries to a thin powdery film pretty quickly. Lots of people here say it doesn't work as well as the liquid, probably because the way it dries makes its penetration less effective. If you apply the foam first, let it dry, then apply K&B solution, you are re-dissolving that dried minoxidil and giving it more chance to penetrate.
It does make sense that you're not absorbing as much minoxidil by using it after K&B. See
Kraemer and Bohn's original patent:
You're applying minoxidil over "flexible films which adhere to the scalp" containing "a plasticizer". Try minoxidil first, then K&B.
