Like some legends making us turn a hair, surprisingly (9)
I believe the answer is:
arthurian
'like some legends' is the definition.
(I've seen this before)
'turn a hair surprisingly' is the wordplay.
'surprisingly' is an anagram indicator (a surprising ordering of the letters).
'turn'+'a'+'hair'='turnahair'
'turnahair' is an anagram of 'ARTHURIAN'.
'making us' is the link.
(Other definitions for arthurian that I've seen before include "Of a legendary king" , "of legendary hero" , "Sort of legend" , "Like legends" , "Relating to the once and future king" .)
