I had my friend cut and style mine like Kairi's. I also liked her hair color, so I died it red. It's funny, because Kairi is one of my least favorite characters, but her hair in the first game is absolutely ADORABLE, in my opinion. I've been thinking of posting a picture of my hair to show what a lovely job my friend did.
I have hair that is like Cloud's in KH2 but without the cool bangs in the front. I can make the bangs but it takes a while and a lot of really glue like gel. Most the time I leave it without the bangs and just push it all back.
