I can definitely attest to being able to reuse the hair. And it looks very natural. You may have to recurl it at times to make it look super fresh. I did my whole head with 1.5 packs maxx. I bought 3 packs so 😂 but it lasted 2 weeks before i felt like the curls dropped but i didnt sleep with a bonnet.
Because this particular video was just highlighting the Versatility of the braid pattern in the back. I have many other yanky twist videos though so you can check those out.
