The supermodel, 42, looked stunning as always in a skimpy bikini, but it was hard to look at anything but her hair — or lack of it.
The normally gorgeous Campbell’s flowing mane started several inches behind her hairline, giving her a sickly appearance.
“It’s hideous, what did she do? It looks really bad! ” Beverly Hills stylist Kazumi Morton told RadarOnline.com.
From the looks of it, her hair nightmare is a case of traction alopecia, a kind of temporary baldness caused by the persistent pulling of hair extensions over time.
It’s likely the result of Campbell’s decades-long use of hair extensions, which have given her a luscious, shiny head of hair throughout her modeling career.
“Whoever put the extensions in, they put them way too close,” Morton said. “They are way too close to the scalp as well, they need to be at least a half inch away.”
Hair extensions are known to cause damage to the wearer, since the process of attaching them to a person’s real hair or scalp through weaves, glue or clips can be extremely painful and traumatic on the hair.
“We have patients who are in their early 20s come in after wearing hair extensions for six months or one year, and they actually have bald spots,” New York City dermatologist Dr. Eric Schweiger told Good Morning America last year.
Celebrities are no strangers to the dangers of extensions.
"Nothing destroys your hair faster than hair extensions," Jennifer Aniston told Harper's Bazaar in 2006. "I decided to have a couple of extensions, never knowing you end up with 400 things in your hair that cause your hair to break off."
Luckily, patients with this condition have been known to grow their hair back within a year of giving up their extensions.
No word on whether Campbell, notorious for her bursts of rage, has thrown a phone at her hairdresser yet.
