Sonali's hair is so shiny that it's hard to take accurate photos with my lame camera. The flash bounces like crazy!
We just got her today. (Okay, so my son got her and he will barely let me get near her, much less brush her hair, but anyways.... ;D) Anyways, her hair seems to be very much like Marisol's. Very thick and deeply wavy. Maybe a bit more prone to flyaways but Mari is at the doll hospital so I can't readily compare. It could just be the extreme lack of humidity in our house right now.
By the way, if anyone is on the fence about her right now, I don't mean to be an enabler, but she is freaking gorgeous! To the point where she may have a doppelganger in a couple months.
