In 1995, Miles Bletchley was said to have cast a jinx on Alicia Spinnet from behind while she was doing homework in the Hogwarts library in 1995. His spell, one of several incidents in which Slytherins jinxed members of the Gryffindor Quidditch team, caused Alicia's eyebrows to grow at an alarming rate. By the time Alicia reached the Hospital Wing, they were blocking both her eyes and her mouth. Professor Snape would not accept the testimony of the fourteen eyewitnesses who saw Miles jinx Alicia, insisting instead that Alicia must have performed a Hair-Thickening Charm on herself, presumably in a botched attempt to gain a fuller head of hair.
Behind the scenes
- This may be one of the hair-regrowing spells mentioned by Miranda Goshawk in her Book of Spells.
- There may exist a separate Jinx with nearly identical effects based on the testimony of the fourteen eyewitnesses who said they saw Miles cast the spell on Alicia, or it may have just been a malicious use of this charm.
- Harry Potter and the Philosopher's Stone (Possible appearance)
- Harry Potter and the Order of the Phoenix (First mentioned)
