WATCH: Want Robin's Wig?

Supporters stood by her as she shaved her head after she began losing her hair to chemotherapy and then again when she decided to ditch her wig in favor of a natural look.

Now, she's hoping to give back with the wig's sale. One hundred percent of the proceeds from the auction will go toward The Bridge Breast Network, which provides services to low-income, uninsured breast cancer patients.

The auction will begin at 6 p.m. ET on Tuesday, Oct. 28 and will continue until Friday, Nov. 7 at 6 p.m.
