Deedle gave you good advise about the scalp issues. When you cowash, you have to use the pads of your fingers and "scrub" your scalp.

If you're using the commercial "moroccan oil" that's not pure argan oil--it's full of cones and you can't just cowash. So, that may be the cause of some of your frizz issues. When you buy products, you have to check the ingredients for cone, zane and conol.
