Russian city once called Molotov; a hairstyle (4)

I believe the answer is:

perm

(Other definitions for perm that I've seen before include "Football pools forecast - wavy hairdo" , "combo in pools" , "A hairdo; Urals city" , "Hair setting method" , "Russian port; hairstyle" .)

I've seen this clue in The Sunday Times and The Times.
