Will minoxidil gunk interfere with iRetore

[titaniumtorpedo]

I am a 61-year-old male with thinning hair top forward and a receding hairline. I have been taking finasteride and last week the dermatologist's PA told me to add Nizoral, minoxodil, and the iRestore laser cap. I told her minoxodil, which I used for a few months last year, makes my scalp very dry and ugly. She said use it anyway. Well in the week since I've been using it some gunk has appeared on my scalp. I'm afraid this gunk will interfere with the laser's effectiveness and since I don't think the minoxodil does anything anyway I'm inclined to drop it. Should I be concerned about this stuff on my scalp? Should I try to scrub it off? Or what?

Propecia and rogain work great together. What do mean by gunk. It shouldn't affect the laser but you are better off with propecia and rogain

What do mean by gunk.

A build-up on the scalp.
