"Brides are into loose, natural-looking styles—they want their hair to appear slightly undone, as if they just put it up themselves," says Armando Sarabia of San Francisco-based Get Your 'Do Up! "Jennifer Lopez's messy updos are romantic and not too structured. She often goes all-out with volume and texture, so I typically tone her styles down a bit. Before pinning the hair up, I'll spray it with a light-hold hairspray, then curl it using a thin flat iron for a smoother, shinier finish."
