Bulk hair refers to hair bundles that are tied with elastic bands at the top of the hair. Bulk hair is considered to be the easiest hair extension to use. This type of hair extension is barely processed too much, so it retains almost all the features of natural hair. One more reason why people love this product is because its price is quite affordable.
Bulk hair is also often purchased wholesale because people can use it in different ways (to make weft hair, to braid, etc.)
