It is indeed sense 2. 
I think this works.

It's probably sense 2, but since ハリ mainly applies to this gloss I think it needs to be separated.
I'll reopen it to remind us to think about ハリコシ.

and many other instances on the web

Found the expression ハリコシ in an advertising pamphlet for hair related services and, after finding explanations and context for ハリ (Katakana) on the web) (顔のハリ, 肌のハリ, 髪の毛のハリ), realised that the database entry needs a small refinement so that "Text Glossing" understands ハリ (Katakana).
I don't think this is really a 4th sense, but I was unable to add this information under sense 1 or 2: here I got an error marked after the added note - please adjust as needed... :) (I am also not sure why/how sense 1 and 2 are differentiated.)
