I straightened my hair and just took a shower , it's not as curly as before will it go back?

Lorraine Massey (founder of curly girl method and devacurl products and co owner of devachan salon) says in her book that even one straightening job can set your curls back and flatten them out. The odor was probably burnt hair, which has a VERY distinct smell. A metal iron does not sound safe for your hair at all. You can try protein and deep conditioning treatments, but if the damage is that bad, you'll probably have to cut it.
