Yep, it's Egyptian. The woman in 4246 is one that I know definitely has it.Her part no is 30 14 4000.
I came across this topic when looking for something else. There is nopw a part number for black 'Cleopatra' hair if Cheng or anyone is interested. It is 30 25 9990 (and costs 0.20 Euro from DS). Thanks to Heather for 'scraping' this information from Ersatzteile-Finden on www.playmobil.de. There are other hair part numbers now available and I will post full details in a new topic when I have done a bit more research....
