Unfortunately, ginger dad can be humiliating (9)
I believe the answer is:
degrading
'humiliating' is the definition.
(degrading is a kind of humiliating)
'unfortunately ginger dad' is the wordplay.
'unfortunately' is an anagram indicator.
'ginger'+'dad'='gingerdad'
'gingerdad' is an anagram of 'DEGRADING'.
'can be' is the link.
(Other definitions for degrading that I've seen before include "disgraceful" , "Small cucumber" , "Causing humiliation" , "Demeaning, humiliating" , "Debasing, demeaning" .)
