Forget the messy bun, this season’s coveted updo is an elegant twist at the nape of the neck. Opt for a center part to keep the look clean and fuss-free. Hairstylist Guido Palau, who created the look at Ralph Lauren shown here, says the key is to build in the sheen by doubling up on products. Use a styling lotion like Redken Statinwear 02 Prepping Blow-Dry Lotion, ($18; redken.com for salons) before blow-drying hair straight, then spritz a shine spray on the updo before misting on hairspray.
