A burnt headdress (6)
I believe the answer is:
turban
'headdress' is the definition.
(I know that turban is a type of headdress)
'a burnt' is the wordplay.
'a burnt' can be anagrammed to 'TURBAN'.
Though, I am unsure how the anagram is indicated.
Can you help me to learn more?
(Other definitions for turban that I've seen before include "Sikh headdress of scarf wound around head" , "Cloth worn as headdress by Sikh" , "Indian headdress" , "Cloth wound around the head" , "Eastern head-dress" .)
