Hair today, gone tomorrow.

Hands up if you love topknots! They are literal lifesavers when you just don’t have time to wash your locks, right? But sometimes our go-to style can actually have a negative impact on our hair leaving it damaged, or worse… leaving you bald.

Diva Hollands, a 22-year-old former ballet dancer from the U.K., first started losing hair when she was just 13 years old, reports the Daily Mail. The cause? Here ballerina bun!

“I had my hair tied up really tight from when I was really little, and looking back at pictures you can see it started having an effect on my hairline,” said Hollands in a statement put out by Dr. Edward Ball, the specialist who treated her hair loss. “Over the course of so many years, it got worse.” Yikes!

According to Ball’s statement, Diva had a follicular unit transplant to reverse her balding. A hair transplant is a medical procedure in which a thin strip of skin with hair growing from it is removed from the back of the scalp and transplanted to an area where there’s been hair loss. Usually hair loss occurs around the hairline, top of the head, and even eyebrows.

The technical term for this kind of balding is “chronic traction alopecia,” which can occur when you wear the same style over and over. “The best way to describe traction alopecia is that it’s due to constant pulling,” says Dr. Sejal Shah, a board-certified dermatologist in New York City. “If you wear your hair in a tight style one time, this probably isn’t going to happen. But over time, that sheer force will at some point damage the hair to the point where it stops growing from the follicle.”  This can cause irreversible damage.

“Most people who develop chronic traction alopecia don’t necessarily experience pain or discomfort when they’re wearing their hair that way,” says Shah. “They don’t really realise what’s happening.”

So, maybe it’s time to switch up your style?
