Anna's "hair" appears to be not completely real.

I'm gonna get flamed on this one.

Looking at her pictures, there appears to be 2 or 3 different types.

The long straight type seems to show two different colors and several different lengths. There one picture with her back against a mirror and it appears to show a third color of hair which looks like real hair.

The long straight type always appears to be "clumped" together which might suggest extensions.

I'll get the fire extinguisher now.
