A 9-year-old girl was barred from coming to school after she shaved her head in support of her best friend, who has a form of childhood cancer. Her elementary school says shaved heads violate its dress code.

Kamryn Renfro chopped off her braids after her friend Delaney Clements, 11, lost her hair due to chemotherapy for her neuroblastoma.

"It felt like the right thing to do," Kamryn told Grand Junction, Colo., news station KUSA.

But her school, Caprock Academy, says it's a clear violation of the dress code, which is designed to "promote uniformity." Kamryn's mom sent an email explaining the situation, but she was told Kamryn couldn't return to school until she grew her hair back or wore a wig.

"It makes me sad because she was really happy to go back to school and show people what she did, but now that she didn't get to, she's kind of sad," Delaney said.

The school's headmaster has agreed to let Kamryn return to school Tuesday, and the board of directors will meet Tuesday night to discuss the situation and the policy.

Update: Kamryn is back in class today. The school told a local news station they're happy to have her back. The board of directors will proceed with its scheduled closed meeting about the dress code tonight.
