- 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 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. However, they do not make the most powerful of wands (unless the wandwood compensates) and are prone to melancholy if mishandled. Garrick Ollivander made wands with unicorn hairs.
- Unicorn tail hairs are used in potions, though their exact uses and properties are unknown. This was commented on by Harry Potter during conversation with Firenze.
- 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.
