I'm a diffuse thinner and as my hair thins I'm realizing just how greasy this stuff really is. Not my hair but my scalp, which is showing more and more, is shiny and greasy. Never fully dries. I've been using Lee's 5% with no PPG. I had read it was the PPG that made it greasy but I don't know if I see a difference. Maybe slight. Does anyone have any other suggestions, aside from the foam? Thanks.
