Pre-2006, color, originally watched on TV (could have been on a cable channel like Lifetime but not sure), think it's a movie, but could also be TV show, English, USA
Stuff that I'm more sure of:
A blonde? Long-haired child about 7-12 was kidnapped and the kidnapper is holding her and an adult woman, possibly brunette with medium length hair, and named China (or it could be the child's name) in a room with a dressing table and mirror.
The scene I remember is the two of them sitting in front of the dressing room table and the woman might have been brushing the child's hair. The woman is on the girl's side, not an accomplice
Less Sure of:
The male kidnapper's motivation was to raise the little girl like a doll? The girl is kept in a room and wears a nightdress/dress type outfit. And the adult woman might have been investigating or she might have been a casualty?
Genre: definitely not fantasy/sci-fi, comedy, etc.; psychological/drama/suspense?
Other details that may have be completely off: the adult woman is surprised to find that the girl is still alive (which is the basis of the investigation detail); the man is in his 30-50s. the child is calm;
