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.
