tear ones hair out

I'm a little stuck... Click here to teach me more about this clue!

'appear distraught' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.

'our hero in a state unfortunately' is the wordplay.
'unfortunately' indicates an anagram (a bad or unfortunate spelling).
'our'+'hero'+'in'+'a'+'state'='ourheroinastate'
'ourheroinastate' with letters rearranged gives 'TEAR ONES HAIR OUT'.

Can you help me to learn more?

(Other definitions for tear ones hair out that I've seen before include "Remove locks in frustration" , "becoming "distressed"?" , "Become angry" , "violently tackling high-level cover-up" , "Show frustration" .)
