PCOS and oily skin/scalp

Hi ladies! I have insanely oily skin & scalp/hair which I've dealt with since I hit puberty. The only thing that ever helped was Accutane and the oiliness came back within a few weeks of ending my Accutane course. For my skin, I use a product called OC-8 which really helps with the oiliness (compared to not using the product) so I definitely recommend that! I apply it in the morning before makeup and it helps control the oil. I haven't found anything at all that helps with my scalp though - I've tried Nizoral, Phyto, clarifying shampoos, dry shampoo. I'm missing out on doing things that I love like camping (I went 3 times while I was on Accutane) and just being able to wake up & go places with my husband without having to shower, blow dry, etc. Have you all found anything that helps with oily hair?
