How much hair you use is based on personal preference and the desired level of fullness you wish to achieve.  On average, you will need about 10oz (284g or about two-and-a-half bundles of hair) for a full install. Keep in mind the the longer the hair length, the shorter the weft, so if you are ordering lengths of over 18 inches you may need 12 or more ounces of hair for a full install.
