Hairy individual crazy to entertain forlorn hope (7)

I believe the answer is:
mophead
'hairy individual' is the definition.
I don't know anything about this answer so I cannot judge whether this works.
'crazy to entertain forlorn hope' is the wordplay.
I cannot really see how this works, but
an anagram of 'hope' is 'ophe' which is present in the answer.
'crazy' could be 'mad' (synonyms) and 'mad' is located in the remaining letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for mophead that I've seen before include "One with unkempt hair" , "one shocked" .)
