Pro Pump is a one-piece, clip-on hair product that will give you endless styling possibilities. Because it is 100 percent human hair, it will match and blend with your natural hair. Our clip-on hair piece is adjustable so you can get the desired amount of volume instantly. With 75 grams of human hair, Pro Pump measures 13 inches long and is assembled from a mesh base with malleable wires and four polymer-coated clips. The clips are specially designed to stay snugly in place once they are applied along the scalp line. Whether you want a subtle volume change or a lot of extra oomph, Pro Pump is the perfect solution.
