Extensions are a great way to get the wedding hairstyle of your dreams, but be sure to alert your stylist before your hair trial. Here’s why: Your stylist will need to place an order for the correct color extensions so you’ll have your own set to curl and mold during the trial. You’ll also want to invest in human hair extensions; they will definitely be more expensive than synthetic extensions (about three times more), but can be curled, straightened, or even colored if necessary. Lastly, make sure your hairstylist is an expert in extension application so you don’t have to worry about your extra strands shifting -- or worse, falling out -- on the big day.
