Strong-featured, and wearing a wig? (6)
I believe the answer is:
rugged
This clue is a double definition.
'strong-featured' is the first definition.
'wearing a wig?' is the second definition.
(I've seen this before)
'and' acts as a link.
(Other definitions for rugged that I've seen before include "fit for heavy duty" , "Having toughness and determination" , "Rocky - well-built" , "Sturdy and rough of features" , "Rough and harsh" .)
