HELP!!!

I'm in need of some doll-hair-care help. So I've had these dolls for a little while now and really want to (finally) fix up their hair and was wondering how to do this in a way that will be safe for the dolls (so as that their hair doesn't get any worse, their face-paint doesn't come off, etc.) Might anyone be able to help? The following is a description of their hair to help you help me:

 

Dawn of the Dance Cleo: Her hair is untouched since being removed from her box and as such has the typical 'helmet hair'.

C. A. Cupid: Also like Cleo, her hair is untouched since being removed from the box. It's not a firm to touch as Cleo's is and can be moved slightly but still stays in shape.

Dawn of the Dance Clawdeen: Her hair feels like Cupid's as I've run my fingers through her hair breaking up the glue that was holding it all together except that it now feels sticky to touch.

Operetta: Her hair also feels similar to Cupid's and is untouched since being removed from the box.

Dawn of the Dance Frankie: Her hair is a mess. Its has a gluey, sticky feeling and tends to slightly retain some of the shape it was in last. I just took her hair out of a braid and lightly ran my fingers through her hair hence the wavy appearance in this pic.

 

Can anyone help me?

 

P.S. If I've tagged you it's cause I know you know a lot about dolly care. If you can think of anyone else who might be able help please feel free to tag them as well.
