If you like braids but want something a little edgier for your wedding, this faux hawk made from a Dutch (inside-out) braid is pretty rad. Click here to see the inspiration for this look. It can have a lot of height and looks really funky if you've got highlights or multicolored hair since it really highlights the braid itself. This is also one of those amazing hairstyles that's likely to last for a good number of hours and you don't have to worry about it going limp. (Insert obvious joke here.)
Cassidy from On Stage Hair Design created a version of this on a fiery mane that looks fantastic. It's just a matter of creating the Dutch braid, securing it at the bottom, and then pulling out the separate pieces without actually pulling the hair entirely out of the braid. You can see the rest of the tutorial here.
