The ponytail -- it's a godsend in muggy, sticky, hot and humid weather. Whether worn messy with face-framing loose pieces and fringe or entirely slicked back and sleek, ponytails are necessary for the hot months when you just want your hair off your face and neck.

Here you'll see Jennifer Aniston and Jennifer Lopez rocked different yet equally stylish versions of the loose and messy style, while Heidi Klum and others went sleeker.

There are so many ways to do this summer 'do that one is bound to work for you.

Jennifer Aniston

The queen of coifs paired her effortlessly chic pony with a deep side part and a singular long, face-framing layer. Her stylist Chris McMillan can do no wrong.

Jennifer Lopez

J. Lo's center part and face-framing pieces on either side worked in concert to create an easy, breezy, messy pony that is easy to copy.

Jessica Chastain

The ginger-haired actress swept up her famous flame-hued locks into a messy, wavy pony that looked like it required little style time and less thought. Even so, it's anything but sloppy.

Selena Gomez

The singer and actress rocked a sleek, high pony with wispy pieces falling at her temples. This style can be casual or dressy for the wearer, depending on her chosen ensemble and makeup.

Minka Kelly

Much like J. Chastain, the actress pushed her locks into a wavy pony, only with a flat, slicked top instead of one with height or volume.

Heidi Klum

The model and judge of 'America's Got Talent' wore her pony high and tight, which is a clean look that can be done for a fancy or formal event or a day at the beach. It can go either way -- but the sole goal is keeping hair off the forehead and the neck and away from the face.
