A side braid on men having undercut is a combination of a rough structuring and styling, and edgy braid. Begin by washing and drying the hair all the way through and making sure there is a lot on top of it to be braided, making sure the sides and the back are under cut. Make a deep side part on which the braid would rest. Light styling cream will help to control, cut a small section of hair along the part. Start getting braided, and maintain tension all the way to the back of the head. Tuck in or wrap the braid in a small elastic. Work in whatever top hair is left behind and into a bun, smooth out the edges of the undercut, and polish.
