Though we've seen similar videos about Western makeup and hairstyles in the last century, the study of such in Iran is not a simple matter of curlers and lipstick. The intertwined religion and politics of Iran don't just influence the hair and makeup of its female residents, they rule it, backing up the law with such harsh penalties that few dare to deviate, at least in public.
An example of Islamic law with regard to womens' style is clearly illustrated in this video between the 1970s and 1980s. Once the Shah of Iran was overthrown during the Islamic Revolution of February 1979, laws with regard to the women of Iran changed drastically. Among the changes were the long, free-flowing hairstyles and modern makeup of the time being immediately transformed in accordance with the modesty requirements under Sharia law.
