12. Grow That Hair
I may as well tell you now, the majority are indeed as superficial as this, but hair is very important if youre going to be playing this intergalactic time traveller. Why else do you think Chris Eccleston only lasted the one series? Ill tell you why. His bouffant was not up to scratch. Paul McGann was forced (literally, I like to think) into a ridiculous wig to cover his shaven bounce for the TV movie, and more recently Matt Smith defied the Hair Rule by shaving his incredible barnet for none other than notorious hair-hater Ryan Gosling. A heinous crime, the only appropriate punishment would be an itchy wig for the Eleventh Doctors final adventure.  Much love already exists for Capaldis hair, with a Tumblr dedicated entirely to it (happily titled F**k Yeah Peter Capaldis Hair), so if Pete knows whats best for him, he will let his locks grow out into the wavy-goodness we all know he is capable of achieving. He is one step closer to being a great Doctor, simply by avoiding the barber shop. But can he beat Tom Bakers curls? No, probably not. Lets not get ahead of ourselves here.
