Edit out first husband - it's helpful to groom (9)
I believe the answer is:
hairbrush
'edit out first' is the definition.
I can't tell whether this definition defines the answer.
'husband it's helpful to groom' is the wordplay.
'husband' becomes 'h'.
'it's helpful to' becomes 'air' (I am not sure about this - if you are sure you should believe this answer much more).
'groom' becomes 'brush' (groom can mean to brush oneself).
'h'+'air'+'brush'='HAIRBRUSH'
Can you help me to learn more?
(Other definitions for hairbrush that I've seen before include "It is used with a comb" , "It supplements comb for tidying tresses" , "Locks straightener" , "Personal grooming tool" , "Grooming aid" .)
