Little mermaid hair is a noun. If a person has little mermaid hair, it often means their hair has been dyed a vibrant, mermaid-like shade of blues, greens, or purples. For example, actress Elle Fanning made a splash recently when she dyed her hair a gorgeous blend of jade and teal.
This style has become incredibly relevant in modern fashion and beauty. The varying colors of little mermaid hair have both aesthetic and cultural benefits. For instance, the color blue can bring feelings of calmness and serenity, while green can provide feelings of nature and abundance. Additionally, the iconic Hans Christian Andersen story, The Little Mermaid, featuring a mermaid who willingly gives up her voice for a chance at love, has been a huge historical influence on the mermaid hair trend.
