Human Transfiguration

"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 to Harry Potter on human Transfiguration

Human Transfiguration is a sub-branch of Transfiguration in which one Transfigures human body parts or an entire human being into another form. As it is more difficult than other forms of Transfiguration, including Cross-Species Transfiguration, it is a N.E.W.T. level spell, taught only to sixth-years and above.

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 of one's hair 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.

Although it is possible to transfigure humans into inanimate objects, 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.
