Unicorn hair produces the most consistent magic of all core types. It is highly faithful, difficult to turn to the Dark Arts, and will remain strongly attached to its first owner. Unicorn hair wands rarely malfunction or fluctuate, though they may lack the raw offensive power of dragon heartstring. They are especially suited to healing and defensive magic. Mishandling can cause the hair to wither or die, requiring replacement, and unicorn hair wands may grow melancholy if neglected.

Approximately 9.00% of witches and wizards have this type of wand core.
