Okay, so I bought one of those cheapo styling heads fom Dollar Tree, thinking I could stick her on my Endless Hair Barbie.
Unsurprisingly, the rooting is bad and sparse. She also started shedding really bad after I removed the rubber band holding her hair.
So she was a little bigger than I expected, though the vinyl was a good color match in-person, lol.
She fit size-wise on a 1/3 body I got off ebay. Her neck hole would need modding to fit. With a 10/11 wig, she almost looks okay. Granted, I had to chop off all her terrible hair to put the wig on.
I'd say the head is really only okay for learning to mod and repaint vinyl heads in 1\3 scale. She would definately need a reroot or wig, though.
