Harrison's Peak

This refers to substantial loss of hair on one side of man's head.

In the earlier stages of male pattern baldness, men can lose a lot of hair on the peaks of their heads. When this receding occurs at an alarming rate on one side of the head, it is known as a Harrison's Peak.

The effect is to leave the man with a gaping chasm on the peak of the head, which they often attempt to disguise with inventive new haircuts.
That bloke has a got a major "Harrison's Peak", poor fellow should get a hair transplant.
