Julianne Hough's intricate up-do maybe easier to achieve than you think!
First braid a side section of hair to the back and secure with pins. Then collect a good section of hair on the other side of your head and twist, hold that into position. Then gather the rest of your hair and twist this including the previous section into a messy bun and secure with pins. The messier and looser the more pro it looks. That's the beauty of this up-do!
