Ok Peel unit from the manikin head or dome ... cut the mesh from around the unit...  make a template of your head area that you would like the unit to cover ....  place the template inside the unit and draw outline... then cut access unit off that you will not be using.... fold the unit inside out apply adhesive and tape around perimeter of the inside of the unit.... then start applying from the front slowly folding to the back to secure on to head  The fibers are to help you blend the unit on the edge of the hairline and edges of the unit so it would be best to apply thin layer of  adhesive at the start point of where the unit ends then stick fibers to that section only ....brush away access fiber hair then cut and blend as  desired
