>>6096432Face-ups and co. don't like regular hair products.
Friend of mine once used regular human products on a wig and it smeared away the face-up underneath, some of it made the MSC turn bright yellow.
If you style the wig, better don't do it straight on the doll.
Styled wigs tend to attract dust though and when done badly it just looks greasy.
I personally don't like the look of styled wigs (I prefer natural fibers anyway), so if you want a certain style better find a wig that already looks the right way.
