A video posted by an ex-ballerina showing her premature hairline reignites concerns about a popular hairstyle: the bun.

Diva Hollands, a British woman who began dancing at age three, told the Daily Mail that she started going bald in her early teens. She believes the tight buns she wore as a dancer may have brought this on:

"My mum tied my hair 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," she told the publication. "I was bullied for my hairline in primary school and then into secondary school, but it got really serious when I was about 13. Since then I was completely self-conscious about it and did everything I could to hide the area. It affected me a lot, especially as I was being picked on."

She continued to lose hair after giving birth to children, and this prompted her to undergo a Follicular Unit Transplantation in October. She started seeing her hairline grow back a few months later.

Bun panics are nothing new.

Last year, dermatologists famously warned that the increasingly popular "man bun" could lead to hair loss as well.

"That longstanding pull or traction on the hair can pull the hair out and ultimately lead to permanent scarring, which is something we call traction alopecia," Dr. Doris Day, a dermatologist in New York City, told ABC News last year.

But do you really need to worry?

California-based hairstylist Christine Thompson insisted to ABC News that there is a way to wear buns without increasing your chances of hair loss.

"You absolutely can get the same look slicked back," she said. "The things to avoid are putting it on damp or wet hair...and also making sure that you really don't pull the hair while it's secure with elastic."

A person's hair type or genetic makeup could also play a role in what buns do to their hair. New York-based dermatologist Francesca Fusco told ScienceAlert last year that buns could be especially bad for men who are prone to hair loss. "If a man already has androgenic male-pattern thinning at the temple, pulling it tight might make it worse," she said.

She added that a loose style could make all the difference:

"Traction alopecia is caused by wearing a hairstyle that continuously pulls really tight on the hair and hair follicles, resulting in such damage that they don’t grow hair anymore. With regards to the man bun, if they’re not pulling it tight, they’re not losing hair."

Dermatologic surgeon Dr. Sejal Shah told Good Housekeeping that people who wear buns should start to worry about potential hair loss if they feel a pull on their head.
