Hello,
I'm mixing the powder into my Pg/ethonol minoxidil solution and it seems to work just fine. Nizoral (ketoconazole) works wonders for the dry flaky scalp, at least in my case.
I do the same I mix it in my liquid minoxidil solution that is already carried into the scalp by the PG/Ethanol. i guess i cant comment on the K&B i dont know what that is. im also thinking of bumping up my RU solution to a 1.20 mg per day ive been on .90 mg per day and have gotten great results for the past 3 years but i think it may be losing its effect or at least diminishing.
