Does anyone have any hair product advice for someone with Asian hair?

My scalp is slightly oily. The area closest to my roots is a little poofy and has random little pieces sticking out. The rest of my hair is long, thick and straight...Sometimes there are "flyaways" from static and the dry air here. I do blow-dry it a few times a week, but I always use a diffuser and never blow-dry it 100%, so it's not "ovedry." Moisturizing shampoos/conditioners and frizz serums seem to actually make my hair worse...

Any help?
