I think drastically changing hairstyles is what women do to act out when they feel out of control.

You would be correct in that assumption. One of the things women will do during times of stress is drastically change their hair - because it's one of the things they can have control over. When online dating first started becoming a thing, back in the early days of the web, someone wiser than me warned me about that: "If her hair doesn't look like her profile pic or the color doesn't exist in nature, run the other way." Adage still holds true to this day, possibly even more so in this age of dangerhair.
