The actress' doctor told ET last month that she was 'nearly finished' with her chemotherapy treatments.

Months after shaving her head, Shannen Doherty's hair appears to be growing back.

The 45-year-old actress took to Instagram on Saturday to share a new photo of herself and her husband, Kurt Iswarienko, in honor of the #loveyourspousechallenge, first suggested to her by her good friend, Sarah Michelle Gellar.

"It's the 6th day of the #loveyourspousechallenge. This is us now," Doherty began her post. "Life has handed us an interesting card with cancer and although we would both prefer to not be faced with such a terrible disease, we must also search for the good."

The former Beverly Hills 90210 star went on to express how grateful she is for the things that she does have.

"Am I blessed? Yes. Blessed for my friends that I have. Blessed that I have a fantastic mom and blessed that this man is in my life," she said. "Cancer gives a clarity that is unique. I've seen friends run, I've seen strangers step up, I've seen the unwavering still unwaver and I've seen @kurtiswarienko there for it all."

"That's friendship," she concluded. "That's love."

ET caught up with Doherty at Stand Up To Cancer's telecast just last month, where she confessed that going through cancer has made her and her husband even closer.

"Cancer has in a strange way done some amazing things for me. It's allowed me to be more me, like much more in touch with who I am, and much more vulnerable and the person that I always was, but I think it got hidden behind a lot of other stuff," she explained. 

"My marriage was always fantastic," she added, "but it's even better now."

And according to her oncologist, Dr. Piro, Doherty is just about finished with her chemotherapy.

"Shannen is doing amazing," he reported. "We have just a few more weeks of treatment, and then we'll be nearly finished with the chemotherapy."
