[Lord of the Rings] Did Gandalf always looks like a wizened old man or was he a dark-haired babe a few centuries back?

He's always (at least since entering the world) appeared to be a wizened old man. That was the form the Istari (wizards) took in order to convey their wisdom and humility for the purposes of guiding the kingdoms of Men.

Remember that the wizards are not mortal Men but immortal Maiar, angelic beings in the direct service of the Creator.
