Well, it doesn't belong to me.
Curiosity got the better of me, and the record seems to be at 150 cm for a girl who is 169 cm tall.
(And holy shit, the "journalist" is just as ignorant, annoying and going for the "lulz, circus freak!"-approach as they all are. So eyeroll-worthy)
It did however make me consider going for length just to see if I could steal the record away. But... Dunno. Not really sure I would enjoy growing my hair competitively like that, you know?
150 cm is just 6 cm below my knee-bend though. Hmm. And of course it was longer than that back in 2014.
