Regularly tenses head after doctor put a bandage on (7)
I believe the answer is:
dressed
'put a bandage on' is the definition.
'regularly tenses head after doctor' is the wordplay.
'regularly' indicates alternate letters (regularly take one letter, leave next etc.).
'after' is a charade indicator (letters next to each other).
'doctor' becomes 'dr' ('Dr' can be a synonym of 'doctor').
'tenses'+'head'='tenseshead'
The alternating letters of 'tenseshead' are 'essed'.
'essed' after 'dr' is 'DRESSED'.
(Other definitions for dressed that I've seen before include "Trimmed" , "Like crab served up" , "Attired" , "Wearing clothes" , "Put on clothes" .)
