When hair extensions are listed as double drawn, this essentially means that within a bundle of hair, the majority of shorter hairs as described above are removed and replaced with longer hairs. This means that if you were to purchase 18" hair extensions, the hair would be thick from root to tip, as the majority of hairs (around 70-80%) within the bundle would measure the full 18 inches

Double drawn hair is a great choice if the hair you are after is that of volume and glamour. As the hair extensions are very thick right to the tip, a full bodied look will be achieved with ease. As the extensions are so thick, it is also likely that you will not need as many as you would for a full head of single drawn hair extensions, and therefore will not need to purchase quite as many strands.
