Hair weave materials can be bought at a wig store that sells synthetic and human hair. The items needed are two to four packs of synthetic braiding hair, two to four bundles of human hair on tracks in the desired texture and color, two weaving needles, two spools of string that match the color of the human hair, two weave nets, a pack of metal banana clips and a parting comb.
Preparation
Wash, condition, trim, blow-dry and moisturize the person's hair, then part it into four even sections. Use the banana clips to pin up three of the four sections of hair. With the remaining section, start at the outer edge of the person's hairline and part the hair into a straight line. Use a banana clip to pin the rest of that section, then combine the synthetic hair with the person's real hair and braid flat onto the scalp (also known as the cornrow technique) until you have braided the entire parted line. Remove the hair from the clip and fasten the clip to the braid so that it doesn't unravel, then bend the part into a spiral going counter-clockwise. Un-clip the braid and continue braiding into the new part. Continue this process part by part until all of the hair in that section is included in the spiral braid. The finished product is one long, spiral braid that lays flat on the scalp and includes all of the hair in that section. The tail of the braid is a small area of hair that sticks out from the center of the spiral. Take the threaded weave needle and lay the tail flat onto the spiral braid, then sew it into the braid so that it lays flat. Repeat this process with the remaining three sections of hair.
Weaving
Lay the weaving net flat across the head. Measure and cut the net around the hairline so that there is just enough net to cover the head completely. Use the threaded weaving needle to sew the net across the scalp horizontally, starting on the hairline at the base of the neck. Sew in and out of the spiral braids from section to section until the net covers the head completely. Unroll a bundle of the tracked human hair and place one end at the left end of the hairline one to three inches above the nape of the neck. Unroll the track horizontally across until it reaches the other side of the head, then cut where the hairline on the right ends. Take the clipped and measured hair track and use the threaded weaving needle to sew the track horizontally across the head in the same location it was measured. Sew the hair track into the weave net, making sure not to sew the hair in the braids below. Repeat this process, going from two to three inches above the hairline at the back of the head all the way to the forehead. Stylists may place the hair tracks in different positions on the weave net depending on how they want the hair to fall, but the process of sewing the tracked hair into the net remains the same.
Maintenance
In order to last for the maximum of three months, the weave must be maintained on a bi-weekly basis. Maintenance includes washing, conditioning styling and re-sewing any tracks that come undone with daily wear and tear. Maintenance should be done in a salon by the stylist who sewed in the weave.
