They might be popular with celebrities like Jared Leto and Leonardo DiCaprio, but the man bun trend might not be as harmless as we thought.
Doctors are reporting a rise in the number of cases of traction alopecia, a condition in which bald patches appear on the scalp, mainly around the forehead. And the culprit is the trendy top knot.
The baldness occurs when hair is pulled over a long time, causing damage to the roots. Eventually, the hair stops growing and never grows back.
“Traction alopecia in men is becoming really, really common,” dermatologist Sabra Sullivan tells MIC. “I see it probably once or twice a week. Unfortunately, once the hair follicle is damaged, it doesn’t grow back.”
The same condition is common in ballerinas and women who tie their ponytails too tight.
Not everyone with a man bun will develop the condition but, as its permanent, it’s better safe than sorry.
To prevent traction alopecia, doctors advise men to make sure their hair is tied back loosely.
"There are lots of men who wear man buns and don't get traction alopecia," Sullivan says. "The idea is not to pull so tight. You don't want to have to go for hair transplants later.”
