What does long hair do to your face?

I am a 16 year old guy and growing my hair out long, maybe even just medium with bangs like zac efron, or a long beachy surfer style. I heard long hair gives some illusion like makes:

1)nose look smaller
2)face look longer
......?????


What are some other ones? Like how does it make your eyes and mouth and chin look? What other illusions does it give off? Will I look more plump and wide with longer hair, because I am a skinny guy and that would be awesome to look bigger? How else will it make me look in the face?
