The purpose of a finishing spray is to seal moisture into each hair so a comb glides through more easily and lifts the coat more evenly. To make it work properly, you must have the right comb for the type of coat you are working with. This will help to lift the hair where you need it for scissoring.
Spritz a little finishing spray onto the coat. Comb it through by using long, even strokes going against the lay of the coat so the hair gets lifted to the desired height. . Shake the area you are working with to loosen the coat. Then scissor. Because of the quick time frame, the spray won’t hurt your scissors! The coat will be straighter and easier to comb through each time.
