As for the hair...yeah they do some amazingly intricate hair styles, and usually its all Gel. The problem is getting one with 'intricate' hair that isnt smooshed or something, Operettas 'Victory Rolls' are really hard to get a good one over here, many are messy in the box, Mine wasnt perfect but she was the best on shelf!
Cupids hair is a plait from her Right ear up and over and secured over her left ear, where it opens and is gelled into her hair.
Toralei was another one with 'Helmet' hair, and I wasnt Brave enough to wash it out in fear of losing her 'Stripes'. But last week I managed to get her 'Cinema Fashion' on ebay so bought a Spare Doll to redress and took the plunge, I Didnt wash her hair out (I may one day) I just brushed it to break up the gel. Has more body but still has her stripes they are just very faint!
and someone asked about the Fashion packs, I only have three but I think they are awesome (Ive actually used the wave 3 Cleo outfit to replace the boring 'Signature Cleo' outfit!)
