A 9-year-old girl in Colorado was banned from school after she shaved her head to support to her friend suffering from cancer, Fox News reported.

After Delaney Clements, 11, was diagnosed with Neuroblastoma -- a rare form of childhood cancer -- chemotherapy treatment caused all of her hair to fall out. To help her friend feel like she wasn't alone, Kamryn Renfro decided to shave her head too.

However, instead of applauding Renfro, the headmaster of Caprock Academy in Grand Junction told the young girl she violated the school's dress code.

Headmaster Kristin Trezise said the code "was created to promote safety, uniformity, and a non-distracting environment for the school's students. Under this policy, shaved heads are not permitted."

Backlash against the school's decision quickly erupted from both girls' parents and complete strangers.

"For a little girl to be really brave and want to shave her head in support of her friend, I think it was a huge statement," Clement's mother, Wendy Campbell, told NBC 11. "It builds character." 

After both families took the social media to protest the situation, the school's board of directors said they would hold a special meeting on Tuesday night to discuss the situation.

Kamryn's mother, Jamie Olson Renfro, thanked supports in a Facebook post on Monday night.

"On behalf of our family, we would like to express our gratitude for the support we have received from family, friends, and complete strangers today. We in no way expected, nor wanted all of this attention regarding the situation at my daughters school. I posted on Facebook just asking for support for Kamryn, and our family as we embarked on a journey to simply change a policy in the parent handbook to include this situation, and allow Kamryn back in class," Renfro said.
