Dense hair causes you to be more vigilant when applying products, so you coat all of your strands. Other then that, it affects how you style (when I was younger and had really dense hair, I couldn't wear it in a single braid--it looked like a club.) Shouldn't really affect ingredient/product selection (maybe more hold?)
