Uma has many different hair style, all of which look great.
Below is just one example of a great looking hair style. Long, golden, wavy locks that go all the way to her lower back. Is this her real hair? Only she knows. That is the beauty of hair extensions these days. No one can really tell if you are wearing them or not. ...unless of course they say you yesterday with very short hair!!!
The long hair style below does have some shorter layers toward the front, but for the most part the hair seems to be all one length.
