A good low-poo will help with both of those problems. A low-poo is a shampoo without sulfates/silicones, basically. Just look for one that contains coco-betaine. A good, gentle low-poo that I would recommend is Renpure Organics, red bottle. This will remove any possible product buildup from your styling product, and help clean your scalp from sweat/nasties. You may only need to low-poo once a week, but might be something to look into.
