I HAD really thick hair lol, its still pretty thick. it drastically reduces the oil and it feels great after it dries but I still get the bad DHT itch though. I have only really been using nizoral for about a month or so, so I'm not as 'full bottle' as it were. Oily skin is oily skin mate it would happen whether you wash it off or not, my derm says it has no effect if you wash it every day you will still produce the same amount, he also thinks that bad diet has an effect on your oil secretion also although I can neither confirm or deny this. I do believe that finasteride or dutasteride makes an overproduction of skin oil in SOME people and I seem to be one of those unlucky people. Best of luck mate!
