The look can be slick and polished or laid-back and messy, and celebrities have been loving it on the red carpet in every kind of style.

Emma Roberts rocks a low ponytail
To get winter’s on-trend look, make sure your hair is poker straight, then comb to the nape and secure with a hair tie. Smoothe over with a little gloss for a sleek finish. Ramp up the glamour by wrapping a section of hair around the ponytail to hide the elastic, just like Emma Roberts has here.
Selena Gomez shows off a messy mid pony
A saviour for bad hair days, this style looks best when a tad rough around the edges. Spritz dry shampoo onto roots to freshen and give a matte finish or use texturising spray for tousled definition. Back-comb a little at the crown, then use your fingers to pull hair into a medium-height ponytail. Gently pull apart the bottom layers of the ponytail to tighten it at the base and push it slightly higher up the head.
Blake Lively rocks a sectioned ponytail
Gather the top third of your hair into a ponytail and secure. Gather another third of your hair and secure into a ponytail along with the first ponytail. Repeat until you have three connected ponytails, and pull each one until it bulges. Finish with styling spray – and start turning heads.
Emma Watson rocks the side pony look
Use a tail comb to create a deep side part (trace a line with your comb from the highest point of your eyebrow and start the part there). Gather hair low, to one side, and secure. If your hair isn’t naturally wavy, add waves with a curling wand and work a little product through the tail for added texture before swishing the ponytail over your shoulder.
