Because it is so important to look your best, you'll want to start looking for celebrity hairstyles early. You can find pictures in fashion magazines or check their websites. Another great way to find a good style is to search Google Images for "celebrity hairstyles." When you find the style you want, print out the picture and take it to your favorite hairstylist.
You don't want to spring a special hairstyle request on your stylist at the last minute, though. Take the photo in when you schedule your appointment, and make sure the stylist you make your appointment with is confident in his or her ability to carry out the style.
