Give yourself an expert updo, no appointment needed. In just four simple steps, celebrity hairstylist we show you how easy it is to re-create a posh side bun.

1. Squeaky-clean strands are not required to achieve this style: This ’do works best on hair that hasn’t been shampooed for a day or two. Just washed and gotta have the look now? “Get instant texture with dry shampoo. I’m a big believer in the stuff,” says Townsend. Flip your head upside down and concentrate the dry shampoo at your roots, then continue to spray all over to add texture. Using the tail of a comb (or pencil), create a deep side part, pulling the section to where the head starts to round.

   

    

2. On the opposite side as the part, section your front strands and pull the rest of your hair into a side ponytail. Secure using an elastic just below your ear. To give the ponytail some softness, Townsend recommends rubbing your fingers together around the elastic, which will loosen its hold and create a tousled effect.

   

    

3. Add some extra oomph by back-combing the ponytail using a plastic comb or a boar-bristle teasing brush. Five or six passes, from the ends to the top of the ponytail, should give strands the right amount of texture and volume. Set hair with a light-hold hairspray.

   

    

4. Looking in the mirror, scrunch the dishevelled ponytail up tight; wherever your fingers are, replace them with bobby pins—eight to 12 should do it. The goal is to keep the look loose. “I love updos that look like they could fall out at any minute,” says Townsend.
