Plus primates have a history of different head fur types (some monkeys have some very distinctive head hair). This makes your species more noticeable over a distance. Standing out on the savanna, look at the other apes over in the distance and you would note they were your species because of the hair on the head. Full disclosure, not a scientist just some guy that thinks monkeys and apes are cool.
