“You can see in Hollywood now actors like Leonardo DiCaprio, Chris Hemsworth...I mean even David Beckham was wearing one, because it’s kind of cool and it’s kind of hot,” dished Yahoo Style editor-in-chief Joe Zee to "Good Morning America."
Dermatologists say the hairstyle could lead to hair loss.
"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," said Dr. Doris Day, a New York City-based dermatologist.
Traction alopecia develops when the hair follicles are scarred because hair is pulled too tight, too often, she said. The hair loss can be permanent.
"Once the follicle is scarred, the hair is permanently lost and that means it won't grow back," she said.
So is there a way to embrace the look without risking your full head of hair?
Expert hairstylist Christine Thompson of Spoke & Weal salon in California said you do not have to surrender your hair bun completely.
"You absolutely can get the same look slicked back," she said.
In addition to avoiding wearing the top-knot in the same spot every time, Thompson says there are two other things to avoid when putting your hair in a top-knot.
"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," said Thompson.
