Colin Kaepernick decided to put his 'fro on hold Monday night while the 49ers took on the Rams -- and broke out a brand new hairstyle ... cornrows!
CK's dome has gone through all sorts of changes since he came into the league -- he's like the black Tom Brady ... only without the Super Bowl rings.
Check out the pics ... keep the rows?? Or go back to the 'fro???
(We vote 'fro ... it was magnificent.)
