Why Leona Lewis stopped straightening her hair

The "Bleeding Love" singer says a health scare prompted her to go natural.

The 32-year-old singer, best known for her hit single "Bleeding Love," shared in a new essay on Glamour.com why she made the change after years of straightening her hair.

Straight hair also made her feel more "polished," she admitted.

After straightening her hair for years, Lewis said she began experiencing symptoms of chronic fatigue, along with pains in her neck and throat, about a year and a half ago.

"It was a pretty hard time, and after a bunch of tests, I found out I had an autoimmune condition called Hashimoto’s disease, which affects mostly women," she wrote.

"When my symptoms were the most severe, I could hear my body telling me that I needed to slow down. I also started to feel tired during performances. I began taking medication but also turned to Ayurveda (my mum is a master herbalist) to help heal my body naturally," Lewis wrote. "I just got to a point where I wanted to start over physically and emotionally. I started eating better and I stopped straightening my hair."

Lewis ended up shifting her entire beauty routine.

The singer had to re-learn how to care for and style her curly locks.

"It was a rediscovery for me that curly hair is actually so versatile," said Lewis, who will sometimes scrape it back in a "super clean low bun."

Now she can't imagine going back to straight.

"If someone said, 'I want to blow-dry your hair straight now,' I would be like, 'No way!' I’d look like an alien," she said. "It just wouldn’t be me."
