When you're a liberal who dyes their hair blue, it's a bold move that signals a strong sense of personal freedom and rebellion against the mainstream. The bright shade is also a head-turner and a style statement that can make people do a double take when they see you walking down the street. However, there are also downsides to dyeing your hair blue, such as the long and difficult process that's required to get the color and the maintenance of it. In addition, it's a color that fades pretty quickly, so you'll have to visit the salon quite frequently to keep it looking vibrant.
It seems that a lot of leftists are dyeing their hair these days, and not just because they're trendy or they want to stand out from the crowd. Many of them are also doing it as a way to show that they are liberals. This trend has become particularly popular amongst millennials who are trying to demonstrate that they are part of the younger generation of progressives.
It's no secret that there is a wide variety of political views within the Democratic party. Some liberals are concerned with things like starvation in Africa, climate change, factory farming, and other issues that are largely abstract and distant from the average American's day-to-day existence. This big-picture thinking can often lead them to feel disconnected from the embodied experience of their lives, and it may explain why they seek to express their identity through wild colors or other visible markers of difference.
