While this ponytail takes just about 30 seconds to do, the prep work begins months before the wedding. After all, this style is all about long and lustrous locks. (Our fail-safe plan in a nutshell? Eat plenty of omega-3's, such as salmon and nuts, or go the extra mile and take the supplement Viviscal. Use a deep-conditioning hair mask weekly, get regular trims to chop off split ends, and ease up on the hair coloring and heat styling!) On the big day, simply add a pretty embellishment, like this one from Jennifer Behr, and you'll be aisle ready.
