Firenze: "Harry Potter, do you know what unicorn blood is used for?"
Harry Potter: "No. We've only used the horn and tail hair in Potions."
— A very serious question[src]

Unicorn hair is a powerful magical substance with a variety of uses, originating on the body of a unicorn. It is frequently shed.


Unicorn hair can be used in wand-making; they produce the most consistent magic, least subject to fluctuations and blockages, most difficult to turn to the Dark Arts and the most faithful of wands[1]. However, they do not make the most powerful of wands (unless the wandwood compensates) and are prone to melancholy if mishandled[1]. Garrick Ollivander made wands with unicorn hairs.

Known uses

  • Unicorn tail hairs are used in potions, though their exact uses and properties are unknown[2]. This was commented on by Harry Potter during conversation with Firenze[2].
  • Rubeus Hagrid found that unicorn hairs could be used to bind bandages.

Wands with unicorn hair cores

Behind the scenes

  • Unicorn hair is worth ten Galleons for each hair, according to Horace Slughorn. However, this may be inaccurate as he was drunk at the time, and a wand (which may contain such a hair) only costs seven. Although, as this seven Galleon price for a wand was established in Harry Potter and the Philosopher's Stone and unicorn hairs being ten Galleons was mentioned during Harry Potter and the Half-Blood Prince, it is possible that there was an inflation in the price of unicorn hair during the intervening years.
