Demiguise hairs were long considered to not have enough oomph to make a proper wand, but with the advent of multiple cores they have gained favor for their strength in Transfiguration and the subtle arts. When combined with a stronger wand core they make potent wands, however, on their own they can be rather one-dimensional and difficult to use for anything but Transfiguration. They have found favor in students of all Houses, although they may be slightly rarer among the open Hufflepuffs.
