I worked in Ainkwa, Erbil for few months with an international NGOs. Something I got a culture shock is. For a woman to walk in the streets with your hair wet, it is considered very rude or rather not very good thing. As you are considered as a prostitute. Therefore do not do that while you are in Iraq.....If you didn't know, you know now...all the best. Otherwise, it is a very nice place and people are VERY nice and polite. I enjoyed my stay there....
