Rogaine & White Flakes - help needed

[montreal6130]

Hi,

I have been on Rogaine since January and really, really happy with the results. I use the foam in the morning in the crown and the liquid (5%) in the evening for the crown and twice a day in the frontal hairline. The results to date have been really amazing (sorry as I don't have pics).

Main Issue

I have a ton of white flakes. If I rub my hands through my hair I have like a snow shower (almost like flipping a snow globe). I have been using Nizoral 2% for two months twice a week and no real slow down.

(1) Is this dandruff or a flake residue from rogaine liquid?

(2) any suggestions on how I can stop it?

thanks,
Eric
