Hair and why it's gone frizzy? (5)
I believe the answer is:
shock
'hair' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for shock that I've seen before include "Outrageous" , "See 18" , "Unpleasant surprise" , "Sudden upset; offend" , "Trauma" .)
