"If only we'd done human Transfiguration already! But I don't think we start that until sixth year, and it can go badly wrong if you don't know what you're doing...."
Hermione Granger[src]

Human Transfiguration is a sub-branch of Transfiguration and a form of transformation in which one transfigures human body parts or an entire human being into another form.[2]

Human Transfiguration is more difficult than any other form of Transfiguration, including Cross-Species Transfiguration and is therefore N.E.W.T.-level, taught only to sixth years and above at Hogwarts School of Witchcraft and Wizardry.[2]

Students of Uagadou School of Magic were especially skilled in Human Transfiguration.[3]

Nature

"They had just embarked upon the immensely difficult topic of human Transfiguration; working in front of mirrors, they were supposed to be changing the colour of their own eyebrows."
Harry Potter regarding the difficulty of human Transfiguration[src]

Horace Slughorn disguised by the use of human Transfiguration

Human Transfiguration can be used to essentially replicate the natural abilities of Metamorphmagi, allowing the practitioner or the subject to take on an entirely different form or make various individual changes to their appearance, such as growing or changing the colour, style or pattern of one's hair[1] or taking on individual animal body parts. However, while human Transfiguration can presumably be performed by any wizard who's skilled enough, on themselves as well as on others, a Metamorphmagus is born with the ability to make such changes to their own bodies with little to no effort and without the use of a wand.[4]

Although it is possible to transfigure humans into inanimate objects,[5][2] it is unknown how someone who had himself transfigured into an object would be able to untransfigure without the intervention of another witch or wizard. Probably, if witches and wizards perform this on themselves, they will do this with the intention of retaining their mental consciousness and abilities. Therefore, they could untransfigure themselves back to human form, both nonverbally and wandlessly.

Emeric Switch contributed an article on the scientific aspects of Human Transfiguration to a 1926 issue of Transfiguration Today.[6]

Dangers

It has been stated many times that human Transfiguration can go badly wrong when performed poorly. The user has the risk of getting stuck in his or her transfigured state.[2]

Behind the scenes

  • In September 1994, when Draco Malfoy was transfigured into a ferret, he tried to get to the dungeons.[14] Complete transfiguration into an animal makes a human think like the animal, except Animagus transfigurations.[19] This suggests that the attempted escape had nothing to do with him wanting to get to his common room and was coincidental.
  • In Harry Potter: Hogwarts Mystery, Professor McGonagall claims that a wizard can use a combination of wandless and non-verbal magic to change themselves back into a human,[20] though it had previously been established that full human transfiguration causes a human to think like the creature they turn into.[21]
