So I've got a Glinda from Arda and I would like to try and tone it down some, it's just too fluffy. On my wig head it looks fine, but as soon as you put it on a normal sized head, it's just like a fro of curls, and doesn't look very good or like it has any length at all. I'd like to fix it, but obviously need the curly style.
Tips for toning down a wig, without losing too much of the curl?
