Problem is, that,ketoconazole cream, use it for long periods of time, leaving several hours, might go systemic. And ketoconzole is not something you want it systemic.I go 0.1% on Tretinoin having built resistance gradually. On the nizoral side I get the ointment on top of the shampoo. I don't have 30 minutes to spare with shampoo on my head and the cream can stay as long as I want.
