Colorful hair is a huge beauty trend currently on the rise. We're seeing it more and more these days, from the covers of magazines, to beauty gurus online.

While some choose to dye their locks a vibrant blue, or an electric green, others select a whole myriad of eye-catching colors that give their head a pop of pizzazz. No one can deny that the trend certainly is attention-grabbing, and has garnered the affectionate nickname 'unicorn hair.'

But what happens when a nurse, shopping in a local store, is openly criticized for her choice in hair color? Does she meekly turn away and try to hide her bold tattoos and rainbow hair? The short answer: no.

The reply this devoted nurse gave to the cashier that openly shamed her for her hair color is fantastic. You'll definitely want to see this one.
