6 Winter Haircut Trends to Inspire You, From Prada Bobs to Pixies

Given its usual summer connotations, any style with the word "mermaid" might seem like an unusual choice for the depths of winter — but Giannetos says it's a perennial style option for long hair. "If you love your long locks and want to enhance them, the mermaid cut may be ideal for you," he adds.

"The key to this look is long layers. It's all about movement and adding dimension to the hair. Ask your stylist to softly frame your face and keep the layers long," Giannetos says. "And if you have naturally wavy hair, it will be easy to style yourself at home." We love a low-maintenance moment.
