These bundles weigh 3.5/4 ounces each. Bundles are single donors and cuticles are all aligned together allowing for no tangling and minimal to no shedding. Please note, each bundle will have similar curling patterns but no bundle is the exact same, that’s the beauty of raw unprocessed hair. Think of it as your natural hair, some parts are curlier and some parts are lighter than others. This hair can be lifted to extreme high lift blonde colors and takes heat really well.
