Separate the hair into sections to indicate the direction of the braids.
Secure three pieces of synthetic hair that are the same color as the hair's roots as well as the same length. Measure out so that one piece is one-third thick and the other portions are two-thirds thick, and wind these pieces together.
Part the section of the hair intended for the braid. Put the synthetic hair in the middle of this section. Braid down the back by weaving the natural hair into the extensions, and attach additional extensions to increase the size of the braids. Cut off any stray strands upon completion of braids.
Lower the tips of the braids into a container of thermal water. Surround the dampened braids with towels to soak up the heat. Massage mousse and gel into the braids.
Run the tip of a rat-tail comb across the top of the head to remove any additional stray hairs.
Apply oil sheen to the hair. Sit under a hair dryer for approximately ten minutes.
Wrap a scarf around the head each night prior to sleep, and remove it in the morning.
