Although he's only been alive less than four years, Luke has managed to master the art of chameleon-like hair changes. I have lost count of the numerous ways he has been able to change his appearance with the mere flick of a brush, wearing of a hat, or night's sleep on the wrong side of the bed.
A few examples ...
Sweaty helmet hair
Pat Riley hair
And the always popular I-do-it-myself hair
A regular James Bond, that Luke. Who knew such trickery could be performed by someone so young?
