Genes can turn on and off. So our "gene" for head growth is on much longer than chimps.

Humans have developed a larger brain.  It is one of the main characteristics that distinguishes the human lineage from other apes.  We did not develop from chimps, but we do share a common ancestor with them aged at 5-6 million years ago.  We have a larger skull to house and protect that larger brain and that causes the forehead.
