Frequent Iran traveller here: indeed, Iranian women usually wear a headscarf "only". Their skin is about as exposed to sun as those of European men/women in Germany/Northern Europe (where you usually do not run around semi-naked due to the cold temperatures). Only very conservative Iranians cover more of the body. Here in Europe, my Iranian wife with her natural darker skin color has indeed a Vitamin D deficit albeit wearing western clothes: the long, dark, cold winters that are mostly spent inside houses let her body not produce enough Vitamin D, so she takes supplements.
