Why does my Yorkie look homeless

Poor little purebred guy is 3 months old, his fur on his head is changing to silver so he looks like he has male pattern baldness. I bathe him weekly and he looks amazing for most of that day but then looks homeless again. Is it because I overly pet and snuggle him? All of your Yorkies look so quaffed and put together. Any secret shampoos, brushing techniques, etc help this poor ragamuffin look more suave?
