Okay, so I've never looked into getting a hair extension, as my hair is naturally long and full. However, I do know women who want some extra length, or feel like their hair just doesn't look right. If I was going to get a hair extension, I believe I would want to go with human hair, as it tends to look much more natural and "right"-obviously for good reason!
