Unaffixed long hair Toga-chan.
(As far as I can tell, ほどき itself isn't a word but 解き物 is. Which means "Clothes to be unsewn, or unsewing" which in this case is in relation to her hair not being in bun's. but the word unsewn doesn't work in English here so I went with unaffixed. And this has been a moment in the life of a translator.
