When she performs in Torino, Carolina Kostner is hair styled by Franco Curletto which is a famous professional hair styler.

She is also sponsored by L'oreal hair products and L'oreal - Biotherm cosmetics, but most of the time, she shows a quite natural make up style ( this actually doesn't mean she doesn't make up at all the ladies know how it works )
I really LOVED her hair style and makeup at Torino! She had very nice hair-do and had stylish silver eyeshadow that went so well with her costume!
Her more recent makeup, however, has been a bit underwhelming to me although it may be just a matter of taste. Sometimes she wears a bit too much eye makeup. I also didn't like her pink eyeshadow that she wore at the SP of her first grand prix event.
I wonder if L'oreal gives her makeup artist along with the products.
