Head in hands, still bald! (8)
I believe the answer is:
hairless
'bald' is the definition.
(similar in meaning)
'head in hands still' is the wordplay.
'head in hands' becomes 'h' (I can't explain this - if you can you should give a lot more credence to this answer).
'still' becomes 'airless' (I've seen this before).
'h'+'airless'='HAIRLESS'
Can you help me to learn more?
(Other definitions for hairless that I've seen before include "Bald" , "Furious" , "suffering shock loss" .)
