'My hair color has never prevented me from treating a patient!' Nurse with rainbow locks pens a furious rant after she was publicly shamed because of her bright strands

Mary Walls Penney, a nurse specializing Alzheimer's and dementia treatment in Raleigh County, West Virginia, has her blonde hair highlighted with vibrant shades of pink, purple, yellow, and blue - a colorful look that matches her self-described cheerful disposition. 


However, Mary was forced to defend her hair - and the quality of her patient care - on Facebook after a female cashier commented on how surprised she was that she was allowed to work as a nurse because of her brightly colored strands.
