My son, too, was a tow-head was little and you would never know it now. Having said that, however, it was a gradual thing. Prince Michael's hair definitely looks bleached to me and to go from that color blond to the color he is now, doesn't seem like a natural progression.
Did anyone catch Dateline (?) last night and the interview with Debbie Rowe? She said that MJ always wanted a blond haired, blue-eyed child.
