Sets topless hair-dos shockingly (6)
I believe the answer is:
radios
'sets' is the definition.
(radio is a kind of set)
'topless hair-dos shockingly' is the wordplay.
'topless' means to remove the first letter.
'shockingly' is an anagram indicator.
'hair'+'dos'='hairdos'
'hairdos' with its initial letter removed is 'airdos'.
'airdos' is an anagram of 'RADIOS'.
(Other definitions for radios that I've seen before include "Sets" , "Communication devices" , "broadcasters?" , "Devices for sending or receiving signals" , "Wirelesses" .)
