I agree that sometimes, "scruffy" can be synonymous with "sexy." But I don't like Wallace Huo's hair in the poster above. It just looks dirty and unkempt.
I don't mind a bit of facial hair scruff but the hair on the head has to be somewhat decent. I am a big hair person. Hence, my constant complaints about Wallace Chung's hair in Rose Martial World.
Hair, hair, hair! Why can't the makeup and wardrobe department just get the hair correct?!
Good thing I'm not an actress, or I'll just be really angry all the time with my bad wuxia hair.
