Sarah Walters had been doing henna for a couple of years when her mom asked her to do a "crown" for a friend with cancer.

"My stepdad passed away from multiple myeloma five months after he was diagnosed," Walters told Revelist in an email. "It was a difficult time that further reinforced my desire to find a way to help in whatever way I could."

"I was excited for a unique opportunity. It was a rewarding experience."

"After that, I knew I wanted to make them accessible to anyone who had lost their hair during chemo."

Chemo can be lifesaving for those fighting cancer, but it's also a very trying experience.

Side effects include nausea and vomiting, fatigue, body sores, and nervous-system effects, among others.

Not to mention hair loss, and the toll that can take on a person's confidence.

"[My clients] have told me they feel more beautiful with their crowns," Walters said.

"In the same way that you feel a boost of self-confidence leaving a salon with a fresh hairstyle, a henna crown provides a similar experience."

Walters comes up with each design in the moment that she's doing it. The process takes about an hour, and the henna lasts for a couple of weeks.

"People are excited to have an alternative to wigs or hats, and it can be empowering."

Lauren Russell, one of Walters' clients, said that the temporary henna design makes her feel pampered.

"For a little bit people don't see that I'm sick," Russell told K5Evening News. "They see art."

"It doesn't look like just a bald head or any of that. It's just pretty."
