Besides helping patients keep some hair, the DigniCap system also allows hair to grow back faster, said Dr. Dipika Misra, who works at Oncology Specialists of Charlotte.
"It does help that they are not faced with their cancer diagnosis everyday when they look in the mirror," she said.
Keeping her hair made going through chemotherapy a lot easier, Smith said.
Recent scans have shown no sign of cancer, Smith said, but she is continuing with another chemotherapy drug that doesn't result in hair loss, to keep treating microscopic cancer cells that are likely still around.
Her thick blond hair is cut to just below her ears, a longer style than what she had been wearing before the treatments.
That was a precaution in case she needed to cover thinning or spottiness.
During the time she was receiving treatments, she had to be careful with heat products, and could not wash her hair as often or dye it.
"I was worried about my gray roots for sure," she said.
But those soon will be gone -- she has a hair color appointment scheduled in December.
