London, Mar 9 : Britney Spears is facing a danger of going bald again, for the troubled singer is losing her hair in clumps.
The pop-wreck has long been covering her patchy scalp with wigs and extensions fitted by top Beverly Hills stylist Kim Vo.
However, from what is evident of some recent photographs, even though most of her earlier hair are growing back, there are frightening bare areas on top of her head.
After seeing rear-view pictures of the 26-year-old star's head, many hair and scalp experts have warned that she may suffer from a serious condition leaving her permanently bald.
According to LA-based Dr Maurice Messler, the 'Toxic' star might be suffering from what is called 'alopecia'-a stress-caused ailment.
"It looks like she could be displaying early signs of alopecia. This can be stress-related or caused as an unforeseen consequence of hairstyling routines, such as excessively tight braiding. In some people, it can also be caused by a psychological compulsion to literally pull or tear out one's own hair," the Daily Star quoted him, as saying.
"Some medical treatments, including certain psychotropic drugs, can cause hair loss or accelerate the effects of alopecia," said a second specialist.
Right now, Britney is under psychiatric care and is taking a minimum of two such prescription drugs as well as pills to help her sleep.
Meanwhile, celebrity stylist Vo has been working on the singer four times a week and is replacing her existing hair extensions with new technologically advanced ones an still holds hope for the troubled star's long locks.
"Her natural hair is now about five inches long and work on her new extensions is a long process but we are looking forward to very exciting results," Vo said.
However, a stylist from another salon, who has also worked with Spears, laments her condition and sees no future improvement in her condition.
"There are several areas where her hair doesn't seem to be growing back at all. And what hair there is is very brittle, almost spiky in parts. It breaks my heart because I don't think she'll ever again have those lovely long, natural tresses she once had," he said.
Other celebrities who suffered from alopecia include the likes of Princess Caroline of Monaco, Star Trek actor Patrick Stewart, telly presenter Gail Porter and comedian Matt Lucas.
