Try a support for facial hair (6)
I believe the answer is:
goatee
'facial hair' is the definition.
(I've seen this before)
'try a support' is the wordplay.
'try' becomes 'go' (go is a kind of try).
'support' becomes 'tee' (I've seen this before).
'go'+'a'+'tee'='GOATEE'
'for' is the link.
(Other definitions for goatee that I've seen before include "A short pointed beard" , "Tufted beard on chin" , "Beard like a ruminant animal" , "Type of beard" , "Tuft on the chin" .)
