If you have one, or you've been flirting with the idea of getting one, embrace it - the bob is back with vengeance right now. Stylist Kaleb Pritchard from Dharma Salon in Ellerslie, Auckland says forget the mumsy-looking memory you may have of bobs, and think messy, with a slept-in edge. He believes the way to sex up a bob is with eye-catching cool colour. Here's some bob-inspo for autumn.

Who can wear a bob?
Any woman that's willing to put time and effort into it.
Who should avoid this hair shape?
Keep in mind a bob tends to highlight the chin, face and jawline. The shorter the style the more those features are exposed. When cut to suit those features, it can flatter your face shape. As far as body shape goes, if you have wide shoulders or a short neck, I would probably recommend a longer or shorter style.
What bob shape and length are on trend for winter?
The length needs to sit between the chin and shoulders. With a slight layer through the interior to allow for movement.
Bob's can be boring, how can you sex this style up?
Adding depth with colour to create tonal differences will spice up a plain-looking bob. Also, playing with the texture, either messy or aim for that "day old" gritty look to hair. Or a sharp structured bob, can be ironed sleek to perfection.
What styling products and tools do you need at home to groom a bob?
ghd platinum styler, $360, Sachajuan Dry Shampoo, $50 and Wella Professionals Eimi Sugar Lift, $25
What is your best styling tip for a bob shape?
Use straightening irons for either sleek finish or to create movement.
