Bald eagle: fly off with cold chill around North (8,10)

I think it could be either:

Which length description are you looking for?:

8,10

follicly challenged

'bald' is the definition.
(humorous term for bald or balding)

'eagle fly off with cold chill around north' is the wordplay.
'off with' indicates an anagram.
'around' indicates putting letters inside.
'north' becomes 'n' ('N' can be a synonym of 'north').
'eagle'+'fly'='eaglefly'
'cold'+'chill'='coldchill'
'eaglefly' with its letters anagrammed with 'coldchill' makes 'folliclychalleged'.
'folliclychalleged' enclosing 'n' is 'FOLLICLY CHALLENGED'.

I've seen this clue in The Guardian.
