"I take very precise measurements of a client's head, then I send the measurements to a factory in Italy where the 3D printing takes place," Danielle Grillo, owner of Transitions Hair Solutions, told BuzzFeed.
"Along with the molds [below], we tell them the exact hair density, texture, color, length, and direction of growth on the client's head," Grillo said.
The piece takes about three months to create. It's made to be antifungal and antimicrobial, and it adjusts to the body temperature of the wearer.
After the piece is attached to the client's head with medical-grade dermatologist-tested adhesive, Grillo styles the hair as any hairdresser would.
Every four to six weeks, the client comes back to the private "hair salon" for a scalp treatment and a hair treatment to keep everything in optimal condition.
"I finally just said to myself, 'Listen, you survived cancer. Just invest in it. It's going to make you happy.' I feel more like a woman. I feel like myself again," Sheri Valle, a cancer survivor and client of Grillo's, said in a video about the process.
"To watch clients come in and be a little bit hunched over, and then watch them leave and see them bloom like a flower, that’s what I love about it. I love seeing what it does for people,” Grillo told BuzzFeed.
